Motherboard doesn't POST

Q: Motherboard doesn't POST

Hello. I'm not entirely sure where to go for help at this point, so I thought I'd try looking for help here. I've got a couple problems with my PC that I need help troubleshooting since I'm not experience enough to do it myself. Also, I couldn't think of how to title this thread to convey the best message in the least amount of words, so I apologize if it's misleading.

It started off with me installing a new PSU, the EVGA SuperNOVA 750 G2. I put it all in, and wired it all up, but I made a stupid mistake by using the same wire that my previous PSU used to plug in my SATA devices. It made since at the time since the old cable fit better, but upon further inspection, the two SATA power cables used different pins when plugging into the PSU. Long story short, my SSD was burned and no longer works. I have reason to believe that my HDD no longer works as well, and now I'm starting to worry that my Motherboard or CPU is also fried. I started my computer up and it went to POST just fine, although it did actually recognize my disk drive, which was still wired to the same wire that burned my SSD. I then turned it off and let it sit overnight since I assumed I would just need to buy a new SSD and possibly a new HDD. However the next morning, after I had unplugged and removed all my SATA devices (being the two storage devices and a disk drive), I turned it on and the motherboard did not POST, and did not even send any signals to my monitor. My motherboard is the ASUS Z97-A, and I noticed that the CPU_LED was a constant red. This didn't bode well for my machine so I turned it off and now here I am. I haven't yet tried plugging in the old PSU to the motherboard/CPU, which I will do in a short while, but I also want to test my new PSU.

So, sorry for the long block of text, but could you guys tell me how I can test how much power my PSU is outputting to each of my cables, and possibly what steps I should take next to see whether or not my Motherboard and CPU are fried?

Thanks for any help anyone can offer me!

Preferred Solution: Motherboard doesn't POST

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

You need to get yourself what is called a multimeter to test your psu. Make sure it is digital. You can buy one at Radio Shack or Sears/K-Mart for little money.

I bought my Craftsman a few years ago at K-mart for $22.00 and it works great.

There are numerous You Tube Videos that will show you how to test your power supply as well as online articles. The rails you want to test are the +3.3V, +5V, and the +12V. Here is a good answer to the ranges that are considered desirable: http://www.tomshardware.com/forum/338363-28-what-correct-voltage-values-power-supply

Recently I got a new monitor for my motherboard (Asus M5A78L-M) due to the old one dying, the reason was that there was no posting to t he screen. It was an OEM, Pegasus motherboard that usually dies out sometime anyway, so replacing it was probably sitll a good idea.
After replacing it, putting in all the cables and things of that matter, it still won't post. I've tried switching the RAM into different slots, but still nothing will show up on the screen.
Everything else works fine, the fans work and the lights are lid up where they should be. THe DVD-Drive does open, but closes a couple of seconds afterwards. Also, other things like a mouse and keyboard light up for a second when it turns on.

I really need to diagnose the problem before I spend more money on this stuff.

A:New motherboard still doesn't post to the monitor?

I would start by checking the monitor and the cable. Switch both out with known working monitor/cable to see if you get a response.

For clarification, did you only switch out the motherboard or did you buy a monitor as well? We need to know exactly what you're trying to do to provide the best answer. I think you're saying you replaced the mother board and nothing is showing up on the monitor, correct?

Have a Gigabyte Motherboard, Model No. GA-K8N51PVM9-RH-NV. Its the strangest thing. I tried to install another hard drive and the Motherboard wouldn't boot--it wasn't the hard drive because I took it out--tried everything, cleared the CMOS (popped the battery out) took the board out. Put it back together and took it down to MicroCenter because I thought the board or processor might have shorted or something--the fans come on, it just won't boot. So he looks at it, does a couple things and gets it to boot.

So I come back, works fine. Today I try to add a new video card--same thing--won't boot. Take the video card out--still won't boot--try everything won't boot. There must be something going on that stops it from booting but for the life of me can't figure out what it is. Any ideas?

Here is a link to the Motherboard Manual:

Hi all,
just got a new motherboard and RAM and set it all up with all my old equipment that used to work. Now the computer does nothing :dead:
All the fans are working and the little front LED is on but the monitor's LED remains on yellow and there's no beep from the motherboard.
If I accidently bent the pins where the chip sits would this cause a no-post. I'm not saying I have bent one/some/all but it has me concerned.
The RAM is a single stick of 1GB DDR2 RAM 5300 unbuffered and the motherboard is a dual channel motherboard but I think it takes single sticks.
The motherboard is an Asrock G31M-S

Any help appreciated

A:New motherboard and no POST

Any board can take one stick, so that's not the issue, if your ram was the problem you'd hear a beep, not sure how many as the number of beeps is different for different bios companies.

Seems like the motherboard is getting power, if you bent a pin on your mobo you should get an error msg at least.

I have a Latitude E7440 which is out of warranty. Nothing comes up on the screen, nothing comes up on external monitor, no LED codes. The power light comes on and, when I plug in an AC adaptor, the battery light comes on. I can also hear the fan running. I tried removing the memory and hard drive but no change.
Normally I'd suspect the motherboard but the power light is always on. As soon as you plug in the battery or the AC the power light comes on and I can't get it to turn off. It's like the switch is stuck in the on position or something.
Is there anything else to check before I order a motherboard?

My system has been up and running pretty well for about 10 months now, but lately I've been experiencing some big problems. It started off a few months ago when it would randomly restart after a while of bring in use. I noticed that the more intense the usage, the more likely it would be to restart (if I was playing a cd and gaming at the same time, maybe with another program running as well, for example). This kept getting worse and worse. However, the other day it simply wouldn't start up at all. I have:
MSI 865PE neo2 mainboard
Pentium 4 3.0 prescott cpu with stock heatsink
1 stick ULTRA 512mb ram
WD 120GB hd
400W ULTRA ps
nVidia 128mb video card

When i turn on the ps, all fans start up fine, the power led comes on, and the hd led comes on for a second. The monitor does not receive any activity and there are no beeps at all. The only way I can get it to POST is if i reseat the cpu, and then it only works one for one start and freezes before anything can be accomplished. When I restart after that it will not POST again. I have tried resetting the CMOS jumpers but to no avail. I have checked all connections and everything is fine. I never overclocked my cpu and always had the heatsink on it and had the fan plugged in, so it shouldnt be that either. Could this be that the ps slowly died, even though fans/leds still work? Or is it more likely to be the mainboard? Or is it something else entirely?
Please help if you know of anything it could be.

Do you have anything plugged in to your USB slots during boot? Sometimes that can slow boot times down.

I have an ASUS Socket 775 P5NSLI MB and a Pentium E6400 processor. I believe everything is installed properly but when I try to boot it up it will not POST. The MB LED is on and the case and pcu fans start up but no beeps or display. Someone suggested this might be a BIOS problem but i cannot upgrade the BIOS without getting the computer to at least POST. Is there anyway I can find out if I need to upgrade the BIOS or if it may be some other problem ? Any suggestions will be appreciated. Thanks in advance.

A:Motherboard Will Not POST

If the bios is not compatable,you will need to use a compatable
processor to update it.
Some motherboards ship with the cmos reset or clear jumper
in a safe position to keep the battery from draining.
You might want to make sure it is in the proper run or normal position.

Hello, new to this site and I'm hoping I can find someone on here who knows what they are talking about. I tried yahoo answers, but either they can't read or have no idea what they're talking about. It's not possible to get into the BIOS when the computer no-posts or hell... even powers on.

I'll copy paste what I posted on yahoo.

About a week ago we had a power surge and after that my computer wouldn't turn on (no fans, no fan self-test, no post). Tried a known good power supply and still no good. However I was still getting a stand-by light on the motherboard so I tried a new outlet and same thing. So I went ahead and replaced the motherboard, figuring the motherboard got fried from the surge (even though there was no physical evidence on the board itself).

Got the new motherboard in, put on cardboard and plugged in the old powersupply (nothing else plugged in...just motherboard and PSU). Still no startup. I've read that some motherboards won't even start without the CPU installed, so I installed the new motherboard in the case and plugged in the CPU+Heatsink/fan. Tried again and nothing (I've tried the switch and manually shorting the power-on pins with a screw driver). Got around to trying it with the known good PSU before buying a completely knew one just in case. Nothing. Took out the CPU again and still nothing.

It's possible the motherboard is DOA but with no physical damage it seems unli... Read more

A:Help with CPU/Motherboard? No-post

The CPU needs to be installed in the motherboard at all times, in order to get any sign of motherboard operation. You can remove the memory, and see if the motherboard beeps, if you hear nothing, the motherboard... or the CPU is bad. Make sure you have all the power supply connections to the motherboard including the CPU power plug

I thought I'd help my fatherinlaw with his older 'puter Using asus p5-a -b, AMD K6-2 550 @ 450 mhz (too many errors @ 550 on three similar machines), I decided to help by installing a USB add-on card so his new copier/printer would connect to the computer. slick install. It picked up the printer and away we went, sorta...
Half way through the secondary software installation, It freezes.
Now it won't boot.. Please insert system disk when asked to boot C,A
during POST, it does not even try to detect the Primary Master.
BIOS recognizes it and under auto assigned the proper size, cylinders, etc.
Using a win98 boot disk, I can see, open .txt files. on C:
I looked up and executed Clear CMOS (CLRCLK in ASUS speak) with the battery out. Tested the battery, it is good. Then I treid the BIOS detect HDD utility. Results above.
The disk is a 20G and it reads (under dir command) 16G free.
These facts make me think formatting is not necessary.
I changed IDE cables
Once, under Win98 bootdisk, it told me C: does not appear to have a valid partition... , so I tried fdisk and it said C: was not a valid drive

Hi all,

Would appreciate some help with this.

I have a Foxconn Motherboard N15235 and problems started with the computer freezing, it would freeze even when making adjustments in the BIOS, so I knew it was not a software problem regarding windows.

I disconnected everything that was attached, hard drives, optical drives, fans etc. Still froze.

I turned my attention to the Ram (4 X 1GB). Removed them all and put 1GB back in, ran a Mem test and all seemed fine. I put second back in, ran test and after half an hour it froze, so I thought Ram problem.

I put the ram into another machine and ran the same test and it was fine, passed the test and did not freeze.

OK, I next put different ram into the Foxconn Motherboard and ran the same test again, passed with no freezing. I started the computer up into windows 7 (fresh install btw) and tested the computer with a stress test, it worked fine for 3 hours with no probs.

I decided to put back in the old Ram and ran the same stress test and after half an hour the computer froze, this is weird!

After all this another problem arose, the motherboard will not post, all the fans come on but no beeps and the digital code reader built onto this MB comes up with --. If I leave the motherboard on for a while then turn it off and try again it will eventually post and boot up.

I have tested the power supply under stress and seems to be stable but could still be a suspect.

So, after all this (and thanks for reading and getting this far) I ne... Read more

A week ago i got a new CPU(AMD phenom x4 9750 95w) It was running at high temperatures under medium to low load (60c @30-50%) So i had purchased a new heatsink (corsair h50) to fix this issue. After a day or two under playing Bad Company 2 for a few hours my computer had shut off. I was able to boot up fine and figured it might be due to temps so i started to monitor them closer. Under full load (100% on occt) i wouldn't go above 50c.

Few days later while playing Bad company 2 it did it again. I thought it might be something with BC2 as it only shut off with this game. Next day shuts off while playing world of warcraft. I booted up and let it sit for a few hours before trying to play bad company 2 single player. This time when i turned on the computer it posted but didn't have time to fully boot before the power shut off again. tried booting again and my computer only turned on for a second. Now i cannot boot. I grabbed a PSU from a friend while i think it may not be powerful enough for my graphics card it will not post.
Taking out the card doesn't help either.

PSU i had was 500w
PSU i am borrowing is 450w

TLDR: Computer wont post on 500w (might be dead/dying) or 450w w/o graphics card

Question: Is my motherboard dead? Should i replace PSU as i replace Mobo? or mobo then psu?

A:No POST, error with PSU or motherboard?

this really depends on the quality of the psu but imo the old psu could have damaged your MB but i would definitely try another psu first to make sure.

I have an Asus motherboard with a Western Digital harddrive (all listed in my profile) that apparently doesn't get past the POST. The monitor never flickers on and there are no beeps from the board. I have even removed the RAM and the exact same thing happened. It apparently didn't even notice the RAM missing. I tried known working RAM in it and same effect. I even unplugged the graphics card and the same thing; its like it doesn't even get to the stage of checking the video or RAM. The keyboard never initializes either. The harddrive is okay, I checked it in another computer. I have also reset the BIOS both by removing the battery and the jumper settings. Any help would be greatly appreciated! :grinthumb

Ram: 16GB (2x8) Gskill 1866
PS: Corsair CX600
Video: Using built in APU

These are the only components i have hooked up right now for troubleshooting purposes. I built the system a couple days ago hooking up only the basics to test. System powered on and let me into BIOS first boot. RAM was reading as DDR3 1333 so i set it to 1866 and reboot. Upon reboot i was able to get back into BIOS with no issues RAM now reading correct speed.
With everything appearing to work i started doing wire management as well as installing the ODD, SSD, card reader, and 2 HDDs. Now with everything neatly tucked and managed i go to turn the system on (with post speaker installed) and fans spin up as well as drives and all case lighting comes on, but, no POST nor keyboard lights or video signal and holding the power button does not turn off the system. I have disconnected everything back down to the essentials short of removing the motherboard from the case as well as trying different ram configurations (one stick, first slot). I've even cleared CMOS thinking the ram speed was the problem, all this to no avail. I have never had to deal with a bad motherboard or processor before so i don't know what signs i would be looking for to narrow down my problem.

I have tried 4 different cpus and 2 differnet motherboards and the boards just wont post. I now have a brand new motherboard and cpu and new memory and it still wont post. The board takes a 24plus 4 pin power supply. The power supply is the only thing they have left in common. I do get power to the board as the cpu fans fun no problem. I was told it could be a short in the power supply. Is it possible I need a new power supply. This one is less than 6 months old.

A:New motherboard, memory and CPU won't post

Posting some system specs would probably help with troubleshooting. You're not giving us much to go on.

If you have tried all these combinations then check that you don't have a misplaced motherboard standoff connectiong with the board.
As a standard troubleshooting procedure I would assemble the the system outside the chassis using the bare requirements for a POST; Motherboard, CPU, cooler, 1 stick of RAM, video card, monitor, keyboard and power connections (24 pin mainboard and the 4 (or 8 pin) EPS 12v). If the board has an onboard power switch then you don't need to connect the chassis power connections to the board. Assemble the board on the anti-static bag the board shipped with, on top of the motherboard box and/or table.
If you leave the PSU plugged in at the wall but TURNED OFF while assembling and disassembling then touching any unpainted surface on the chassis occasionally will dissipate anu accumulated static charge
Get the PSU tested. Age is not the only determining factor to consider in a failing power supply. Build quality, physical damage and bad luck can all play their part.

I recently bought a motherboard for the HP xw8600 (FMB-0701)  and I can't get it to POST. Right now, the motherboard isn't grounded to the PSU case, (it's in a wooden case) there's a Xeon E5410 in each socket, a 4gb stick of PC2-5300F in XDIMM1, a GTX 280 in the first pcie2.0 slot, and a heatsink on each processor (not secured, just sitting there, no cpu fans either.) I have an EVGA 600B powering this system. There's no fans connected whatsoever, no front I/O connected, no front USB, no audio, no case speaker, nothing. All power connectors (24-pin, 8-pin, 6-pin) are filled, as well as the GTX 280's power connectors. When powered, the green light on the motherboard come on. Jumping the power button pins (6 and 8) doesn't do anything, niether does hotwiring the PSU. Also, in the corner with the Sata and SAS ports, there's an unmarked set of two pins with a jumper on them. Not sure why, or if it even matters. I need to know if there's anything else that has to be connected to the motherboard for it to POST, or if I just bought a dead motherboard. I'd like a definitive resolution before I throw money at more parts. Thanks for reading.

Hey, i got my Gigabyte EP43-DS3L motherboard today, so i put all my hardware in the motherboard, as you do. All working fine in the old motherboard apart from the CPU which was brand new.

I'm almost sure i connected everything connectly, but when i start up it just spins the fans and LED comes on, the graphics card fan is much faster and louder than previous too.
I don't get any image on my monitor and there are 4 LEDs that say Phase next to them on the motherboard

Phase 1 is green, phase 2 is green, phase 3 is orange and phase 4 is red. I'm not sure if that means anything.

I made sure her old processor was compatible with it. ( AMP Athlon XP 2600 ) I made sure to get the heat sink compound gooped it on there before installing into the new motherboard and put the fan on it put her Memory onto the new board as well which worked wonderfully on her old board ( 2 x 256MB PC-2100 DDR RAM ). I set the jumpers to 133MHz instead of the default 100MHz Processor speed. I put the connectors onto the front panel header for the led lights, reset, power, ect. I connected 1 maxtor 20g HD to the Primary IDE Connector slot then to the HD itself And then connected the slave section of that cable to the cdrom. I then Hooked up the power supply 350w ( Also New ) to the mother board attached the power connectors to the cdrom and the HD. hooked up the cpu fan to the motherboard. Then put the keyboard, mouse, and monitor onto the back and sat back thinking she's going to be so happy when she gets home.

I power it up and the dam thing wont even post it shows the processor AMD athlon xp 2600+ and the bios version thats it. I can't even get into CMOS. I get the quick beep like it's going to start like a normal boot but thats all i get.

Okay so here's the story,
a friend came to me with an emachines T2824 desktop which wouldn't power on anymore, after a little diagnosis of the power supply and all peripherals I concluded that the motherboard was shot. So I ordered a new Biostar P4M80 from Newegg, after installing the new mobo and hooking everything up, it posted and booted just fine and I got into safe mode so I shut the system down and proceeded to connect the HDD Led and Power LED to the mobo and finish putting it back together.. Now all the sudden it won't post anymore. Fans are spinning, drives work, but no keyboard lights and no video signal! I've tried swapping in a compatible CPU and PSU, tried booting with just CPU/Ram/HD and still no post, no beeps, nadda. Even tried clearing CMOS, no luck.. Any ideas or did the motherboard just randomly fail? Power was disconnected while I was messing with the LED connections so I know I didn't short anything.

A:New motherboard, won't post anymore

so you didn't replace the power supply that caused the problems in the first place? Hmmm...... looks like you shot the new motherboard now too.....

AS some may have noticed, I have been having lots of trouble with my PC for a few weeks now. To cut a long story short, with power to the PSU the PC will not start when the button is pressed. No fans, no nothing. This has changed from a couple of weeks ago (got worse) whebn the PC would start as long as the power was left connected to the PSU, or the PC was switched on and left for 20 mins before pressing the start button had any effect.

The only way to get it to start now is to frig power to the fans etc. by bridging on the MB header, everything starts up and after a few cycles of restarts the PC beeps once (when it sends Signal to monitor), fires up and runs perfectly normally. At this point the bridge can be removed and normal operation persists.

Previous ramblings are on another post:


After eliminating most things I decided to change the PSU as that seemed the most obvious solution. Probably guessed that this didn't work. I do not have any power problems now (600W PSU), but anyone need a 400W dual fan??

So whats left?...............Motherboard
But if the PC runs normally (including 5 hrs of video rendering yesterday with no hickups) what is stopping it starting? It is not asking the PSU to start for soome reason.....but I don't know why>
I like this board, even though its a few years old now so any ideas gratefully receivd

Hi All,

I've got a PC that doesnt POST. The PC consists of the following items:

Intel E8400 CPU
Asus P5Q-E motherboard
Gigabyte 9800GT 512MB Video Card
Corsair Dominator XMS8500 RAM
Seagate 500GB SATA HDD

I've had only the essentials connected (ie, no hdd, dvd connected to power or sata) but didnt have much luck. I've tried all components together (CPU, Video Card, RAM and PSU) in another motherboard and it all works well.

Now, the motherboard LEDs still all turn on, the power buttons all work as they should.

So could you please give your opinion on whether it is definitely a motherboard issue as i need to send this board back to the place of purchase. thanks.

I just swapped out my motherboard in anticipation for a new processor (one of the new AMD 8 Cores) but wasn't ready to buy the processor yet. I went with the GA-990FXA-UD3 Gigabyte Motherboard. Everything powers on fine but nothing happens with the post. I don't have any beeps or anything except that all fans are running. Everything turns on but I get no post beeps and of course no visuals on my monitor.

I have the AMD Phenom II x6 1090T processor. From what I can tell I don't have a BIOS problem with that. The MB is version 1.1 and I see that it ships with an F1 BIOS. The F1 BIOS is the initial release and this CPU is already supported in that. So as far as I know it's not that and it worked an hour ago with my other MB (ASUS M4A87TD EVO) perfectly.

I have tried using two different memory module brands. My old board used 16GB (4x4GB) Patriot Sector 5 PGV38G1333ELK DDR3 1333. I tried 2 of them in DIMM1 and DIMM3, nada. I tried just one in DIMM1, nada. I also tried (the memory I bought for this board) Corsair CML16GX3M4A1600C9B (4x4GB) kit. I tried all 4, DIMM1, DIMM3 and also just DIMM1 with no luck as well. The good news (I think) is that when I take out all memory and try to turn it on, I get 4 long beeps. I know the speaker is working. In the manual (and online) I can't figure out what 4 long beeps means. 1 long and 1 short is supposed to be a memory problem, and I'm not getting that with no memory installed.

Hello all, I hope someone can help me cause I am having problems with the D815EEA2 Mbd from Intel. I'm starting to feel real stupid, and angry at Intel for making these "foolproof" boards. This board has been running in my system with a Celleron 950, 512mb, ram for almost 4 years without any hitches.

I recently bought a new case and decided (for s&gs) to migrate all componets. After completetion, I plugged the PS to the wall, the mb started immediately (did not wait for me to press the pws) with all the fans, drives, but there is/was no post, no video, nothing. The STR LED appears, very, very dim and rapidly flashing.

Steps taken thus far:
I have stripped all drives except FD, PCI cards, the AGP card, and tried with the onboard video, tried swapping out ram, I have removed the battery and config jumper for 1 hour and still no luck. I have tried my original PS, nothing. I have even tried pulling the whole thing from the case and setting it on my wooden desk, nothing.

Any help would be greatly appreciated...if it is toast...it's toast...but I need some more opinions...TIA

A:Motherboard Will Not POST D815EEA2

Sounds like you have exhausted all avenues of troubleshooting. The only other thing I could suggest would be to swap the cpu, ram, and video card to a known working board. If it posts, you then know your board is dead.

I would guess that some damage occurred to the board while you were fitting it to the new case.

Hello guys. Cherry post

I just tried putting in a mobo that I got off a guy about a month ago.

Its a Soyo-6vba 133. Its ATX

Seems like it will be a great board once I get it running, IF I get it running.


I changed this motherboard with the soyo.
And It won't boot at all

The mobo has an LED on it so you can tell its getting powr and the cpu fan starts up.

I have tried it with just a pci vid card and an agp vid card. Both known to be working.

I have tried in with 3 different ram chips. In 2 different banks. It recommends the ram in the 4th slot if its by itself which I did and I tried the 3rd slot. All the ram is good cause i'm runnning it right now.

I reseated the CPU 3 times, and its this cpu so it works too.

I tried with just the vid card, ram and cpu plugged in and nothing.

everytime nothing and somtimes the powersupply would shut itself off after 3-7 seconds but most times not.

I get no video at all and no beeps at all. The hard drives spin up but don't do anything.

Since all the rest of the parts except the MoBo are known to be working, does this mean the Mobo is probly dead?

I made sure all the jumpers are in the right spots.

Could it be a bad ground? Some say to use little ceramic spacers when you put it in but the old one doesn't use any so I didn't use any.
I'm pretty stumped. Like I said it was used and I can see it being hard to get my money back off the guy.

Does anyone know if SOYO is cool? cause I have no recei... Read more

Hi there,

This has been my first PC build, which was a pretty daunting task for myself. I will list my specs below that SysInfo retrieved.

The title basically explains it, every now and again, the PC will not show the ASUS Bios logo. It will not get past this black screen stage until I hold in the power button to turn the PC off and then boot it back up again. My keyboard and mouse have LED's in them, so I know if the LED's light up, it will boot normally. If they don't light up, I know I'm going to have an issue.

Being a ASUS P8Z77V-Pro motherboard, red LED's light up one at a time to (assumingly) test each component for errors. Whenever the computer has decided to do it's weird not-reaching-POST thing, the DRAM_LED is lit solid red, and will not move on to any component no matter how long you wait. I don't know if I have faulty RAM, a faulty motherboard (which I'm quite frankly dreading, and I mean honestly dreading, I've got too much pressure on myself at the moment), or some issue.

I'm not an expert, but I'm fairly clued up on technical jargon. I do not believe I've made any mistakes whilst building this PC, but I hope someone can help me here.

Many Thanks,

In the last month i had occasionally a BSOD whenever the pc was inactive(OS is Windows 10).
I decided i was going to change the HDD in a few months(as an analisys confermed it had some errors because of age).

The situation changed 3 days ago: in the morning i started the pc and (before booting) it automatically started to diagnose and repair the system(don't know why).
After that it restarted and the nightmare began;now the pc continues to restart every ten seconds while showing on screen the BIOS (without text).

Here are the parts of the PC

PSU:Corsair RM 750W
GPU:Nvidia 1070
CPU:Intel i5 3330
RAM:8G 2Rx8 DDR3 1600 U
MOBO:Gigabyte GA-B75-D3V rev 1.2

After some researches online i found out that the pc doesn't POST,i tried many things,included the ones i ffound in this list

This are the results:
1)The manual doesn't say anything of importance
2)All the cables are correcly connected
3)I am doing breadbording on a non conductive surface
4,5)Checked,the results are the same if i use the integrated graphics or the old 950 or the 1070
6)I can't access the BIOS and i only have one stick of RAM.I tried all the 4 slots
7 to 10)OK
11)Ok,photo provided
12 to 14)OK
15)Breadbording so ok
16 to 21)OK
22)Tried integrated graphics,behaviour doesn't change

Most importantly:
I cheked the mobo carefully,no signs of damage appear.
With only CPU installed,i hea... Read more

I have an HP 8300 Elite Small Form Factor Desktop Computer, Intel Core i5-3470 3.2GHz Quad-Core, 8GB RAM, 500GB SATA, Windows 10 Pro 64-Bit.

The problem is the computer will not Post and the fans will spin very fast for few seconds then stop. Followed by power light flashing and a series of four short beeps (repeats 5 times). After the beeping stops the power light flashes continuously.

I bought and replaced Power Supply, Ram and battery for the CMOS with no avail. I also tried a different HD, removed, clean and install a processor but the problem still persists. Also, the motherboard components show no physical damage.

What else can I try to solve this issue?

I have an Dell Optiplex GX260 that isn't going past POST. It ends with "press F1 to continue, F2 to enter SETUP" (or something similar) Pressing F1 does not good, it just repeats the phrase. Entering SETUP shows that the HD and CD is unknown. The date is correct so the battery is probably okay. The HD is probably wiped, but I can't be sure at this point. (The other HDs on the Optiplex computers we received were all wiped.) With the CD listed as unknown, even if I got the computer to move forward, I would be unable to install XP. I tried changing the HD but it made no difference. I also checked to see that all cables were connected. The RAM was seated correctly and worked in another computer.

I won't be back at PCs4People until Thursday, but any ideas you have for me I will try to implement then.

A:Doesn't Get Past Post

Welcome to BC CaroleAnne

Sorry to hear about your problem, you have come to the right place - I'm sure we can shed some light on your problem!

Just some things to consider:
- How long has this problem occured?
- Any strange messages prior to the comptuer failing the POST?
- Did anything strange happen prior to the problem?
- What operating system are you using?
- Does the computer make any beeping noises?

Am I right in thinking that your computer has a set of four lights on the back panel labeled A, B, C & D?

Hope this helps so far!!

Pc seems to be booting but doesnt post anything to the screen. I bought a new ddr3 ram and a used motherboard.
What I tried
-clearing cmos
-removing battery/replacing battery
-plugging to the motherboard and gpu
-checking the sticks one by one on different slots

The psu, cpu, gpu and the monitor are fine because I checked if they worked on my old mobo so it seems like its the motherboard or ram. Any ideas on what else I can do before taking it to the repair shop (trying to avoid that due to covid).

Pc specs :

Hi all,

Hoping somebody may be able to help a newbie out with an issue I'm having.

I have a computer that won't enter into it's post. When powered up, the fans all run fine and it will even display video, but it just freezes at the "Biostar" display screen.

Motherboard = Biostar M7SUA

This started happening after a software upgrade that required a reboot, but I have a suspicion that this is more of a hardware problem rather than a result of an upgrade to software since it doesn't even go into post. However, the computer worked fine up until this reboot was done.

Wondering if this is a possible bios issue and how to proceed. Any thoughts or suggestions?

My computer won't POST. I plug my RAM, CPU, PSU and let my Mobo lie on static paper, connect my keyboard and monitor, and my computer will still not post. All my parts are brand new.


Mobo : Asus P5GL-MX
CPU: P4 S775, 2MB cache, 800FSB
RAM: 2x 512MB PC3200, 400mhz
PSU: standard 20pin + 4pin 420W PSU

I'm leaning towards a problem with the motherboard, but i have a hard time believing that it won't work, straight out of the box. I ruled out the possibility that the connection are properly made because its kinda hard to miss where the power supply goes.

Can there be a problem with the thermal greese? wouldn't that cause the computer to shut down?

anyway, ill appreciate all the help

I have seen this thread somewhere on this site before, but the problem was never solved

kept saying no results found.

are most beep codes similar across all mobo makers???

I posted about this a few months ago, but the problem seemed to have fixed itself so I hoped all was good. Nay, it seems.

I put this PC together over a year ago, it's a dual boot machine (two HDDs) with Win 7 and Linux Mint. A few months ago, I rebooted to switch OSes and...nothing. PC was on but there was no MOBO screen and nothing was loading. After waiting about an hour and fiddling with it some, it booted up normally. It was okay until the other day when I restarted and it would not boot anything up at all.
I cleaned it out, reseated the heat sink/CPU, hooked it back up and nothing. All it would do was turn on and that was it. No POST, no error messages, no BIOS, wouldn't load off disks...
Today, I was just messing with it again (just turning it off and on to see if it might come up) and lo and behold, it loaded everything up. Of course, now I don't want to restart or turn it off again.
What I'm wondering is, would this be a MOBO issue and should I replace it?


RAM: Crucial 2 GB 240 pin DDR3 (2)
Video: XFX HD-435X-ZAH2 Radeon HD 4350 1GB 64-bit DDR2 PCI Express 2.0 x16

When I turn on my PC, it does one of two things.

Most of the time, it will power on for only a second or two before powering down, not even making it to POST. The other 1 time out of ten, it will get to motherboard splash display and freeze on a green screen immediately after.

I've ruled out PSU, ram, graphics card and overheating related problems. How do I tell whether or not it's a CPU issue or a motherboard issue when I do not have a spare for either?

Any help would be appreciated.

My computer would not start up all of a sudden. The power light comes on but no sound is heard. I decided to replace the power supply but it does not seem to be any better, I pulled the battery and tessted it also, it seems OK.

I have pulled all connections and cards to reseat them.

I changed exchanged the IDE cables

The weird thing is this, if I leave one of the drives IDE connection unplugged, it will power up. What does that mean?

Regardless there is no POST or Beeps.

If a Power supply burns out can it damage the mother board?

Any Idea's???

I recently purchased a new motherboard, an asus p5wd2-e premium. After installing it my computer acted strange at first which i expected because the asus tech support guy told me it may. After restarting it a few times it eventually worked fine for about 3 days.

Then I was fiddling around in the bios and all I did was switch on some Ethernet cable checking test or something and that caused a whole world or problems. As soon as I restarted, the computer froze at one of Post screens that said something about Marvel (the ethernet manufacturer). No matter what, it would freeze at this screen every time, I couldn't even get to BIOS so I did the only thing i could think of and cleared the CMOS.

Now when I boot up, all the fans turn on, power seems to be flowing fine due to the fact that even my graphics card fan is working, but my mouse, keyboard, and monitor are all not being detected and obviously that prevents me from doing anything. Where do I go from here? What other options do I have to fix this?

first off i have a 450watt power supply, amdxp chip(2.6?ghz i think), abit an7 mobo, and some 2 sticks of mushkin ram 512mb.

ok so heres the problem. over the last 2 years since ive had this rig it has randomly rebooted 4 or 5 times with the siren type sound from the motherboard speaker. also whenever i have had to add new hardware be it sata HDD or dvd drives whatever when i try to reboot i get 2-3 seconds of fans spinning and then it will die again and the siren sounds goes off. this also happened during power outages etc, but not when i restarted through windows or the reset button on the case. normally after anywhere from 20 mins to 2 hours i could reboot and it would just seem to kick over and startup and then it would run fine for days. anyway i went to change a video card today and decided that i wanted to get to the bottom of this problem.

after a few hours of powering off and rebooting i couldnt get it to boot and it fails at post about halfway through the power up sequence with a CF error, which has to do with the readwrite status of the bios (from what i have read)

anyway i took off the mobo and made sure it wasnt touching the case etc. cleaned all the part. still no boot. right now all i have connected are the processor 1 stick of ram and the heat sink. took the heat sink off before and noticed the thermal pad was pretty much destroyed (after 2 years use). i know i need a new one or some paste. but my question is, is it possible that it wouldnt post/boot...

I am just going into a meeting, so I didn't really read the details. I'll come back to you in a few hours, but the first thing you need to do is get some thermal paste.

Without it, the CPU can't transfer its heat to the heatsink. You currently have NO thermal paste/pad? Don't try to turn on your system any more, until you have some thermal paste in there!!
