PC boots but doesn't post

Q: PC boots but doesn't post

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
-breadboarding
-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 :
-q9550 cpu(cooler master hyper tx2)
-gtx 750ti 2gb
-gigabyte ga-g41mt-s2p
- 2x 4gb 1333 mhz ddr3 (cmx8gx3m2a1333c9)
-mx500 ssd
-corsair cx 450

Preferred Solution: PC boots but 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.)

Hey everyone, I'm in dire need of some help with my PC. The computer turns on fine, and boots up (can hear the windows start up tune) but I can't see anything on the monitor. Here's the details:

I was playing a computer game on friday, and during that it crashed. I have no idea if this is when things started or not, but I restarted and it was fine.

On sunday I had another crash, only the screen flickered once or twice and there were green pixel lines going from top to bottom of the monitor , about 2 inches apart in a perfect pattern. When I restarted, there were no graphics on the monitor. The light was flashing indicating it was on power saving mode.

I took the computer apart, unplugged everything, and put it all back together, and for whatever reason it worked fine for about 6 hours.

The next day I turned the computer on, and it loaded fine, but shortly after there was the return of the green pixel lines, with the added addition of the top left corner of the screen being filled with green pixelated triangles in a perfect pattern. These were flickering furiosly.

I tried restarting my computer, and again I got no graphics posted to the monitor. However the computer booted up fine, and I heard the start up tune, and 5 minutes later I shut it down by pressing the "Power Off" button on my keyboard.

I tried another monitor and again, got nothing. I then tried taking the computer apart and putting it back together again, only this time it didn'... Read more

A:Graphics card doesn't post any graphics to my monitor, computer boots up fine

Its usually just the graphics cards, they do fail especially if they overheat - then video card fan not speeding up might have been the problem - most are dynamic and should actually speed up under load. Depending on the manufacturer of your 8800GTX you might be able to get it replaced under warranty if they have a 3 year or greater warranty.

Problem: Upon system startup, power comes on, but nothing else--no beep to indicated the system has entered POST. After several tries, it will finally beep and the harware will come to life.

Once working it will usually keep working as you'd normally expect as power cycle to work. It's mainly after sever hours of being off and now always, over night that the error occurs--no power to the hardware, until several tries.

History: Recently been hit with many Trojans & viruses. They've made it past my NAT router, past my software firewall and have taken apart my McAfee AV program. But they have been contained, before they could do any damage, so I hoped, except I just got a bounced email yesterday, that shows I have been spoofed and my address book copied and is being sent to.

It's an oddity.

I have some new computers I'm setting up, and was getting ready to configure wake on lan, to test implementation. You have to usually find something in the BIOS to configure, before configuring it through Windows (if I've rady right).

I can't get into the BIOS, because I have no POST/splash screen from the vendor for hit DEL or F12 or whatever the key is. The computer boots all the way into windows just fine, though.

Where's my BIOS? And how do I get back to it? I don't think I've ever seen a computer (Macs excluded) boot without the option to get into BIOS on boot. I must have missed something...

Hey. I was concerned following a random shut down and subsequent inability to boot.I had initially been given an error message in POST after reboot stating that my PC had been shut down by ASUS anti-surge protection and I had assumed it was due to my power supply and/or lack of surge protection (surge protector, UPS).

However, after doing a quick hardware check it seems that my RAM might have a hand in my problems. Initially, when I tried to boot my computer it would turn on, but there would be no display and it would turn off after about 10 seconds without POST/BIOS. After checking my hardware and finding out that the D-RAM LED was flashing red I removed both RAM sticks which allowed me to boot and the conputer stays on however there is still no display.

My temperatures seemed fine and I've tried using both RAM sticks in all 4 DIMM slots and completely without to no avail. I've replaced my older GPU, CPU and motherboard and I'm still having the same problems. Also just bought a new PSU because it seemed to be the most likely culprit but I'm still having the exact same problem.

I'm honestly stumped and would greatly appreciate any advice whatsoever. If I've missed out any info please don't hesitate to ask!

Hi all.... another perplexing problem..
PC is just over a year old: elite k7vmm mobo, Athlon 1900xp, 256 ddr333, 40gb maxtor, cd-rom, floppy.
It's not exactly overused or abused but the other day it would not 'turn on'..
It POST's no problem but won't display anything to do with windows (xp)..just sits at a blank screen.
So far I have tried:

safe mode
last known good
vga mode
different psu
reset cmos
run memtest
run powermax
different monitor
different video card (mobo has onboard - tried agp, ati rage pro)

All thats left is to run around screaming and drooling unless you can help..

I have noticed the cpu seems to run very hot and fluctuates.. between 55 and 65. I know thats fairly safe but it still seems very hot and unstable. Heatsink doesnt seem clogged and bios reports fan running at over 4000 revs..

So.. any ideas oh great ones?

cheers!

A7M266 bios 1.07 512 RAM Win XP Home - Sometime ago my machine started acting up I.E. the screen started falshing and while in Windows the bios screen appeared. My keyboard stopped working. Through the batteries had died. Hit the reset button while replacing the batteries. Now when I boot the screen remains blank until the Windows welcome screen appears. After that the machine seems to function. I get all the beeps/FDD noise. During boot I've tried the "delete" key to access the bios - no go. Tried a floppy with aflash.exe & latest bios drop - no go.

Hi,
I have a Dell Vostro 3460 purchased several years ago. It shows the exact same issue and behavior as described in http://en.community.dell.com/support-forums/laptop/f/3518/t/20003103.
If the machine starts up, everything is fine. But it takes a reasonable numer of power-cycles until POST comes up. The problems arised several months ago and the effect seemed to increase over time. At first, the machine was occasionally not booting. Currently, it is the other way round. It occasionally boots up only.
At one time beeing lucky and getting the machine through POST I ran the diagnostics with Fn+POWER. No issues found except that it complained about the missing battery, which indeed wasn't installed at this time.
I also tried
- Disconnecting the hard drive -> no change
- Replacing the RAM -> no change
- Removing the RAM -> beep code (as expected)
- pressing D+POWER -> display test runs (I see colors) -> no POST
I would very much appreciate your assistance. Thank you!

After assembling the computer, I tried turning the computer on but nothing appeared on the display and there was no post beep. I could hear the hard drive and dvd drives spinning, so they appear to be working. The case fan and motherboard fans came on, so the motherboard seems to be powered and the power supply must work.

Afterwards I disconnected both the hard drive and dvd drive and turned the computer back on but it still didn't work. Then I tried removing both ram cards and after I turned the computer on, I heard 3 beeps. beep-beep-beep-pause and this repeated. I then tried each ram card individually and in different slots. But this got me back to where I was having no post beeps.

I put my video card back into my computer to make sure that it was still functioning and that I didn't shock it or anything, and it worked.

I have a HP/Compaq nc6000 laptop that is a few years old running Windows XP. All service packs, etc are up to date.

Sometimes the laptop boots up normally and works fine and sometimes it doesn't. After pressing the power button, the power light comes on, the fan starts, (I think I hear) the hard drive spin and then it all stops. The power light goes to amber (charging) and then it turns off.

Typically when it boots properly, at the very beginning, the number lock, caps lock, and a third light all blink together, then turn off and it boots. When it's not going to boot, these lights don't even come on. (That's when I know it won't work.)

I've tried re-seating the memory. That worked twice but now I think it was just luck.

The first time I opened it, I also pulled a huge dust bunny from the fan. The rest of the insides were pretty clean and dust free. I blew everything out anyway.

Before this started happening, the machine was having some weirdness waking up after hibernating.

The problem happens sometimes after I shut it down properly and sometimes not. It's also booted up fine after a crash.

I've tried setting all the power controls to everything always on and leaving the computer on. But sometime in the middle of the night, it powers down. (I don't know whether this is a gentle power down or if it just shuts off instantly.)

Hey guys, this is fairly long so bear with me...

Came back to my PC the other day, and it was turned off, when I had left it it was still on. To cut a long bit short, I discovered it was the fuse in the plug for the PSU power lead. So I replaced the fuse, turned on the mains, and BANG - PSU blew up (while it was still installed in PC).

Took it out, replaced with other PSU - started up PC and it would boot OK, and give me the single beep, but then would stay on a black screen and not proceed to the Windows splash screen.

So I tried booting into safe mode, this gave varied results - sometimes it would freeze when loading the various files at that black screen, other times it would actually let me log into Windows but then freeze straight away and I had to reboot.

So I booted from the windows cd-rom, and it would get as far as saying "Setup is loading Windows" or similar, then freeze.

Next, ordered another hd, removed old one - installed the new blank one, ran the Windows bootable cd, and this time it installed Windows fine. There I was thinking everything was now OK - not so. The PC was very unstable and kept crashing while installing new programs and using programs etc. I've gone back to it today, and now I am having the same problems as the previous hard drive. Windows won't load either way, and I can't even re-install from the Windows cd-rom as that freezes like before as well.

Basically all this leads me to believe it's gotta be something... Read more

I am not Even Sure if Its Freezing

There is a computer of a friend of mine. We took every single piece out and cleaned the dust on the pieces. After putting everything back together, it doesn't boot up properly. I see the bios screen than it asks me if where to boot, I choose HDD option. Then windows xp asks me what type of start up i want to go with. I chose normal, safe mode, safe mode with command prompt but whatever i chose didn't matter, it didn't started up.

When loading with safe mode option, it always freezes while loading amdagp.xxx file. When loading with normal mode option, i see gray bar at the bottom progressing and when it gets fully gray, there suppose to be a windows logo but instead i get a black screen.

I thought it might be the hard drive damaged and replaced it with another hdd of mine which also has xp professional on it. But it had the same problem. What are the possibilities? What can be wrong? Computer is HP Pavilion XT928.

Thank you

Okay, I've fiddled with this for a while now, a couple days ago when I turned on the computer I would get an error message saying how system/config (something like that) was corrupt. I then googled this and did not really find a solution for it. Almost all of the people that encountered this problem did not know where the source of the problem was. I figure I would give reformatting a shot. After formatting, I figure that I can now use my computer with no worries about more problems but then now different problems appeared.

When I turn on the computer sometimes it would boot up nicely with no problems at all but sometimes it would not boot. The computer hangs right before the windows xp flag appears with the loading bar under it. What I see instead is a different loading bar (DOS style) that spans the entire width of my screen. I thought maybe this was just a problem with my installation of XP, so then I go and boot into my Ubuntu installation (I use grub bootloader and the two OS's are on their own partitions on the same physical drive) and the Ubuntu freezes at the loading screen as well. I went through testing each component of my computer afterwards.

I figure that my processor should be okay since I managed to get this far while loading the computer (I could be totally wrong on this part). I also tested the RAM with memtest86+ that was on the Ubuntu disc. I finished one pass with no errors so I guess the memory is okay. The graphics card should also be okay si... Read more

I can not find any other information out there other than setting shell to explorer.exe which it has been the whole time. It was never c:\windows\config\lsass.exe or anything like that.

Someone said they fixed it by running msconfig, unchecking explorer.exe, restarting, then rechecking explorer.exe [at least thats how I read it.] When I run msconfig.exe I do not even see the words 'explorer.exe' to uncheck at all.

A:My Documents boots, Explorer.exe doesn't.

Hi -

"Explorer.exe" is probably in thousands of registry keys in English, binary and hex form. Not knowing how Explorer got this way makes finding a fix all that more difficult. I have a feeling that you may have done additional damage with the registry cleaner(s). I will just say that you really never need to "clean" the registry unless instructed to do so. They are not errors that were "fixed", rather lost file associations that account for about 0.1% of the total registry keys.

If the registry cleaning was not to long ago, it is likely that you still have a system restore point on hand and can restore the system back to that time. I suggest that you do so. Then run the system file checker/ repair utility - SFC and see if it helps with Explorer.

START | type cmd.exe into the start search box | right-click on cmd.exe | select run as Administrator | the black command prompt ("DOS") screen will appear | type the following:

Code:
sfc /scannow
Upon completion re-boot to allow files in use to be repaired.

I tried booting into safe mode but it restarted again.

Finally i made another attempt but this time it would just show me an error "drive read fail. Press alt+ctrl+del to restart"

I then tried to scan my hdd with seagate hdd diagonistic tools, it detected 19 bad sectors, but when i tried to repair them it dint work, i mean it would just stay on the first sector and the text "TESTING" keeps blinking.

Hello,
I would greatly appreciate help with my problem. My PC, an Acer Aspire AM5641-U5630A with Windows Vista, only starts up sometimes. When I press the power button, the blue power light comes on and the fans start sounding. However, after it quiets down there is no beeping noises and a display does not come on. On times in which the computer does turn on, a beeping noise is heard and an Acer logo display comes on before it proceeds to start up like normal. Once I'm past the Acer logo the computer works fine. It seems to be random as to when it powers up but I have tried an upwards of 20 restarts before.

Thanks,

I'm kind of stuck here...

First what happened: last night my computer froze so I turned it off and then back on. However, when I did, the monitor just remained in standby as if the computer was not on. Everything on the computer seems to be working ok (fans going, lights on, etc). I also don't hear any beeps during the startup.

I've been browsing a lot of forums trying to figure out what is wrong, but I'm somewhat lost. I don't know that much about computers...
It seems some of these forums say the main culprits for a problem like this are the graphics card or the motherboard? Is this true?

Since every thread always has someone asking for specs - here they are:
Intel i7 940
Asus p6t intel x58 chipset sle/crossfirex mainboard triple-channel x
800w power supply
1 TB SATA II 3.0 gb 7200rpm HD
3 x 2GB DDR3 PC3 PC1333
1 x EVGA nvdia gtx 260 896mb pci-e
windows vista home premium

What I've done so far:
I have tried unplugging it and holding down the power button in the front for about 1 minute. 90% of the time this did nothing. One time it started to boot correctly with the monitor only to freeze during the windows load up bar and 1 other time it didn't even make it that far...

Daughter brought her HP DV9500 (Vista 32bit). Very suspicious of malware. If I check the BIOS, it does not see the hard drive (nor does that option appear in the boot menu). However, if you boot the machine, it will load Vista and allow you to log in. After about 10-30 seconds usage, the keyboard and mouse buttons freeze and what was on the screen still remains with that bloody awful circle going round and round.

I'm running winxp, ASUS A7N8X mobo, I had to get a SATA controller card to run this drive. I overlooked that this mobo doesn't have SATA connectors.

Hi...I'm not sure where to put this request, thought since the Dell Inspiron 15 is running Windows 10 (including latest update) that there might be a conflict between the desktop and the keyboard down in the nuts and bolts somewhere. I can turn the machine on, the capslock light comes on, SOMETIMES the keyboard works well enough to input the pin to get the desktop booted up. Sometimes I have to go through steps to get the touch screen keyboard up in order to input the pin. However, as soon as the desktop is active, the keyboard no longer works. I've updated the drivers, don't know what else to do. When I try a search online for a solution, I get differing ideas on how to solve the problem. I've tried resetting the BIOS to default settings, that didn't work. Any and all help will be much appreciated. I really need the keyboard to be working, my kids do their homework on my laptop.

Thanks in advance for any help.

Problem now is that during to boot process it wont see the HD. If i go into the bios and leave it on Auto select for where the HD is it'll show, but it takes about 30seconds to do so. I cant boot with a start-up disk either, for some reason it wont. i changed boot sequences unpluged things nothing will work. I cant flash the bios becuase it wont read for the A drive. I cant get a A: or a C: prompt. the only thing i can get is a BOOT FAILURE ERROR.

The disk is a 20G and it reads (under dir command) 16G free.
These facts make me think formatting is not necessary.

Hello.
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

3)I am doing breadbording on a non conductive surface

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.

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

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,

Hi,
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?

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?

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.

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!!

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
