New Build, Mobo green light, psu powers case fans off mobo, not cpu fan no beeps

Q: New Build, Mobo green light, psu powers case fans off mobo, not cpu fan no beeps

Putting together a build for a friend, however, I believe the motherboard may have been damaged or was damaged upon my taking part in the build. I assembled the parts, a 430w thermaltake psu, an asus mobo, e5200 intel processor, western digital hard drive, 2 gigs of GSkill, ati hd 4850 gpu and an LG dvd drive.

Posted, gave an error message about cpu fan error, I google it, it seemed to be relatively harmless. While in the bios the computer's signal disappeared, I attempted a reboot to no avail. No error codes, cpu fan stopped spinning. Removed memory, no error code, removed 4850, no error code, case fan connected to the motherboard spins when powered on, motherboard shows green light, no signal detected,

I tested the processor in another rig, and it worked fine, and the cpu fan spun fine. Tested another power supply with said motherboard and the motherboard fan would not spin and it would not post, and no error codes. Is my motherboard dead? Any help would be greatly appreciated. Thanks.

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.

Hoping to get some sympathy there....seems like there are lots folks who know what they are talkin about so any help is well appreciated.

Story is:
Dell dimension 440 from 2001....was ran off a generator which would abruptly kill power to the computer a lot. Think this needs to be mentioned. Started having problems gettting the computer to turn on...resolved it by shaking and beating the hell out of it(Actually it was more of an opening and closing of the housing, ). It actually worked.... about fifty times. Finally it is no more...there it sits...I opened it up, cleaned with compressed air, checked all connections multuple times, took out all PC cards, disconnected all drives, keyboard, mouse, moniter, and nothing but a green light on my mobo, no fans, no beeps...SHOW ME THE WAY!!!! PLEASE PLEASE PLEASE....

- could it be that stupid little watchlike battery that has been in there for six years now...)

- a bad switch that turns on the computer (not the one on the back of the PSU)....is there a way to override this switch? loop the right wires together?

- what else?????

A:nothing but a green light on my mobo, no fans, no beeps...SHOW ME THE WAY!!!!

An Honorable death, Then Computer Heaven

If the fans don't start the 12 volt rail of the power supply could be bad.
And I suppose it could be that stupid little battery which, incidentally, HOLDS ALL THE INFORMATION in the BIOS. This is all I know. Sorry about the Caps.
Sure, just take the 2 wires off the on/off switch and splice them together, like stealing a car.

Just moved to a new apartment and now my custom rig won't power on.

The mobo light is green.

When I try to power it on via the button, every powers on (fans spin etc) for a second then shuts down again. It won't power on again until I flip the switch.

I checked the voltage setting and it's at 115 which is right since I'm in the US. I had tried 230 once when I found it wasn't turning on and it stayed on, but I powered it off since that shouldn't be the setting to use.

Any idea what this would indicate? What causes the power to instantly shut off?

Story time: a few years ago I started upgrading my pc an hp a6244n I bought a cpu and a gpu GTX 550 ti And an Intel e7500 the gpu worked but the cpu did not because the mobo could not support it so I bought a mobo that could i.e. (P5b-vm do) but the chord for the power button did not match so I recently bought a case to get it all working a rosewill fmb-01 and got it together only to find there's a green light blinking on the mobo when I went to plug it in I also bought a PSu Rosewill 450W 80 PLUS GOLD Certified Power Supply CAPSTONE-450 Black

Howdy, I'm at my wits end here, and I was hoping one of you could point me in the direction of something else to try.

Working on friend's 2003ish eMachine (ick), because his motherboard chipset heatsink fell off. Used some thermal adhesive to stick the sucker back on, but when i hit the power button, nothing happens. However the motherboard led is on. So I pop in another working PSU that I had laying around, with the same thing happening.

At this point I figure the motherboard got fried, and ordered a no name gateway oem motherboard. I throw it in, and have the exact same issue. I try shorting the power pins to see if it was my power switch, and nada.

It might be that the processor was killed, but wouldn't the psu fan start up in that case? Or I ordered a dud motherboard with the same symptoms?

At this point I'm just not sure what step to take to resolve the problem. Any advice?

A:New Mobo LED green, PSU/Mobo fans won't spin

Run the motherboard outside the case with just CPU and memory installed. See if it starts. If not, the CPU could be fried or you have a defective motherboard. I hope you didn't use the old power supply with the replacement motherboard, if you did, you probably fried the 2nd motherboard

MB - ASUS P5B LGA 775 Intel P965 Express ATX Intel
CPU - Intel e4400 Dual Core

Computer been running rock solid for 2 years. I didn't do any changes. One morning I boot it, front green light flashing together with red. Removed everything and I realized issue is between the MB and CPU. When I remove the CPU cover the PC has no green light, solid red, but when I put the cover on the green light flashes insteed of being solid green. This is very sensitive area it seems. I managed to put some weight on the cpu with a screwdriver tring to get a solid green, but this lasted only for few almost a min, then resets and trys to reboot again.

What could be causing this flashing green light rather than solid on front case? It's not the PSU since I tested it with another one. Also If I put the GPU I can hear unstable fan noise. Its like its struggling.

Other things to add. Thermal paste could've damaged the CPU or the pressure from the cpu cooler that I tightened maeby way too strong months ago. I am 100% I can't do anything to fix this. I know Il have ro replace one piece. Problem is Im not certain which one and no way I can find out...

I read that case fans can be installed on the motherboard or PSU. When installed on the motherboard then you can adjust the speed, however the motherboard would need to have enough power to keep the fans running or else some might stop spinning.

I will be getting the GA-990FXA-UD5 and either the Corsair HX750 or HX850. I will be using 5 case fans.

Does the motherboard have enough ports or channels for 5 fans? I heard that there are some converters for more fans or something like that. Heard a guy say it on YouTube, but he didn't say what type converter.


A:Which is better: Installing case fans to mobo or to PSU?

Generally a motherboard will provide 4 fan headers for connecting fans. CPU. POWER and 2 x CASE/CHASSIS. If you are running more fans and are not concerned about having them speed controlled by the motherboard you can connect them directly to the PSU. Several splitters are available for connecting more fans to the motherboard. I used a splitter that allows 3 fans to be connected one header on the motherboard and a connection from PSU for extra power ( http://www.overclockers.co.uk/showproduct.php?prodid=CB-031-AK )

This was for the use of the H50 Corsair water cooling unit when I had 2 fans running in push/pull configuration on the radiator connected to the CPU fan header on the motherboard and the pump housed in the casing above the heatsink part connected to chassis fan header with no speed control enabled as it is required to run at full speed all the time. This cable allows the motherboard to control fan speeds.

Although a more basic splitter without external power connection or speed control will most likely do the job ( http://www.overclockers.co.uk/showproduct.php?prodid=CB-013-AK&tool=3 )

Hello everyone

This is my first post, as well as my first build attempt, so please be gentle.

P4 3.0 ghz
480w psu
1 stick MD4412UOE 512MB DDR-400 PC3200 Power Memory
Integrated Intel Extreme Graphics

I purchased all of my parts from newegg, and i finally found the proper time to put everything together. After getting a cpu fan that was too big, i purchased a AeroCool cpu fan. I had to remove the P4 retention module, and I now have the fan installed. I installed everything else (cd-rom, hdd, disk drive), and I turn the power on, to find that nothing is happening. I have taken the mobo out of the case to make sure it isnt grounded, and none of the fans power up. The only indication of power I get is the green stand-by light located between the second and third pci slots, and the keyboard lights flash on, then off. Whenever I turn the power switch on, the same thing happens with the keyboard and the rest of the mobo.
I have a buddy who is also putting together his own build, and he said that it was strange to hear that not even the psu fan is starting up. The psu has two power receptables, that I can best describe as female and male. Dont know if this makes any difference. I dont know what to do, and I was wondering if this sounds even remotely familiar to anyone. Am I missing something with some of the jumper settings, or does it sound like a huge problem?

I build the computer last night, spent lots of time making sure I followed all the directions. Spent about 20 mins wondering if I should turn it on to see if the processor fan would turn. After a few ciggys I finally build up the courage to turn it on and it all lit up wonderfully. Power light and case fans came alive CPU fan turned and the monitor flickered to life. Went through the BIOS and set the DVD Drive as the boot disk so I could install Windows XP.

Restarted my PC and it asked me if I wanted to boot from CD or HD went for the CD option and started the Window installation, it then said that it was a new HD and needed to be formatted I said ok and at 5% I realised that I was actually installing Windows ME by mistake. Being the stupid person I am I turned off the powersupply switch.

A:[SOLVED] No Fans No Post but has green motherboard light!

Read other 16 answers

I installed a new motherboard, and it does not seem to be getting power. The green light is off.

When I first installed the motherboard, it was connected to the old power supply. When I would plug it in, I got a clicking noise, but nothing else. I figured since it was only a 250w psu, and motherboard manual states 400w+, I put in a 500w power supply. Now I get nothing. Not even clicking noises. The whole thing wont even run POST. Literally, nothing happens when I plug it in, or click the power button. Yes I tried the switch on the back of the power supply. It's active PFC.

I just installed a P5G41-M LX2 motherboard
I installed a 500w OCZ stealthxstream2 power supply

I already connected the 24 pin and the 4 pin power cables.

Can anyone please give me some advice? (to at least get the green light on)?

I would try a new processor or new ram, if this showed any signs of power going to the motherboard at all.

A:No mobo light, new PSU, new mobo

Well, I don't know about a motherboard that requires "400 Watts". I think that the CPU, and even more importantly, the graphics card combine to set the tone of how much power is likely to be drawn.

Moving along, the "clicking" you heard could be the PSU cutting out due to a short circuit. Check the board to case standoffs, and make certain every one you have in place, has solder lands under the screws. (These are intended to be grounded). If there is no solder land under a screw, remove that particular standoff. BTW did you hook up the ATX (4 pin) connector, the plug near the CPU, and did you connect the PCIE- 6 pin connector to the video card? (This assumes the card you're using needs one)

That bad news is that you may have damaged the board, if indeed it was a short.

I have an old system but it has been reliable. Yesterday I put a new fan and heatsink in. Turned on the power switch. The system powered up for about 10 seconds and went dead. I stripped it down to nothing, including no CPU. Turned on the switch, the main PS fan runs continuously. I put in the CPU only and the PS fan turns off in 10 seconds. This is way too fast for the CPU to be overheating. I put in two other CPU's, same result. Did I maybe hit something on the mobo that causes a short when the CPU is in? Thanks, Tom in Montana

I built a new server recently.

Pentium D 3.0
2 gigs ddr2 800
asus p5rd2-vm

The mobo is supposed to have onboard video, so no video card is in it.

I'm getting no post, (originally assumed it was silent) no beeps (even without ram), nothing!

I rma'd the board (which is what it sounds like), then after newegg supposedly fixed it, they sent it back and guess what it doesn't work.

I bought another board, same kind. Same symptoms. I took out the pentium d and replaced it with a known working lga 775 p4 3.2. Nothing!'

Changed out the power supply with a known working 450 watt ps, the one that I took from my main pc, and still fans work, but not post.

I added a pci-e x16 geforce 6800 and still nothing.

The only thing I can think of is maybe the compound that came with the processor. It was very light on the chip, predone by intel I guess. Didn't require manual adding of compound. But then, I think, if I added a p4 and it didn't work either, why would that be the problem?

I'm really mad right now, I've replaced so many things. These are the thing I know for sure work: PS, mobo, HD, DVDrom, fans.

I'm totally lost, I've never had a problem with asus boards until now. Help would be greatly appreciated.

A:New build, fans, no post, no bios, no beeps :?

Concidering you know PS, Mobo, hdd and others work, all I can think of is CPU. It could also be the RAM, although I find it unlikely that both sticks are faulty. What brand etc is your ram? Make sure its compatible with your motherboard (ie: Voltage).

Hello this is my first post, hope i am in the right spot. If not I am sorry.

I am running a AMD2800 with 2.5gigs ram on an asus a7n8x-x mobo. about a month ago was having some major issues with the cpu speed. Come to find out the mobo has some blown capaitors.
So I replaced the mobo (an asus a7n8x-x) with the exact same model. Like an idiot i thought it should be too easy with the exact same mobo.
Hooked everything up, powered on, pcu and fans run, hd, disk drives, video card, then 3 sec later powers off (LED on mobo stays on).
I have tried powering on with only 1 ram stick, same results. No burn marks or anything on mb to indicate a short. Thought maybe i fried my processor, but i hooked me old mb up (the one with blown capacitors) and am on that now posting this.
I am at a loss, any advice?

Hi, I having alot of different problems with my Gateway GT5464. I got onto IE and after a few minutes I heard 3 beeps and the PC shut down, but not all the way. I still had the power light on, on the tower, the key board and the speakers. The screen then went into a "plaid pattern". I shut down by using the main power switch on the surge protector. I installed a factory Gateway restore DVD. On start of this it said "Windows is downloading files". That bar maybe went 25% and stopped. I went and used the F10 key for boot and still no luck. By chance I used safe mode to get on IE. That's where I'm now. I have been having problems getting onto IE from normal mode. I have found to start in safe mode and select "start in normal mode". Which was woking for awhile. Any help with this? Thanks

Ok, so I'm building my first rig, I have a Corsair 500r case and ASUS P8z77-v LK motherboard and the fan connectors from the case are 3-pin and the motherboard has 4-pin connectors. So are there adapters that I can get to plug the mobo into and the fans into?(like both sides(mobo & fans) need their pins to plug into an adapter is what I'm getting at) Is it that easy? I went to a local parts store and the guy there told me he doesn't have anything like that and I should probably buy new fans and I really don't feel like that is the only option. Everything else I looked up regarding this cases fans and this specific mobo has nothing to do with the connectors so its leaving me to believe there is a simple solution that I am just missing here.

Just left my pc unattended for a few minutes. When I returned it was still online (at TSG) with nobody else having touched it.

Suddenly a deepish intermittent beep started from inside. As the side was off I located it near the front of the case. Also the keyboard had gone haywire - forgive the definition. Pressing most had no effect, pressing the space bar caused pc to shutdown .

The beep was not the sequential type you can check up on at the Amibios site - it was deeper like the 70s TV Games if anyone remembers them

I rebooted ( no beeps) and went to Device Manager - the K/B was there ... no reds / yellows and according to trouble shooter was functioning normally - the same error with key functions occured.

I removed k/b and put in another (this one) and all seems well. So far the beeps have stopped.

Has anyone any idea what could have caused this ? Overheating ?

Fans seem to be ok and they and heatsink are clean.

The Mobo - Gigabyte GA 7N 400.

The previous K/B - Office K/B non USB.

The K/B I put in is a regular K/B with a USB Connector.


I know the Ram is ok - 1 stick of 512 PC2700

The only card in place is my GeForce 440 and thats seated correctly / with no display problems.

Nothing has been spilt in the case / and nothing touched without earthing first.

CMOS Battery not loose / incorrectly installed.
Just like to know if this is a sign something's on the way out ...

This just started happening last night (while I was sleeping apparently cuz I left my comp on)

Firstly when I boot up now, the mobo will start to beep every 1-3 seconds. Then it runs XP and continues the beeping on the XP load screen I could begin to see something wrong because every time it beeps, the system seems to freeze for the duration of the beep (sort of like a 1 second lag).

When XP finishes loading and all my startup application finish loading, the beep stops. Everything looks fine then. But if I try to run ANYTHING or do ANYTHING, the beep returns. But only if something is loading. For example: if I try to open MS Word, the beep returns, but stops once MS Word finishes loading. Again, the beeping is accompanied by the annoying lag, effectively slowing down the system. (I'll get a series of beeps in a row if the system seems really busy).

In essence, if the system is busy AT ALL, the beep and lag can be observed.

I suspect it's a RAM problem... any ideass? what I did was I took my RAM out and put it in another spot, but the problem persists... Or maybe it's a power problem?
Please help got a big paper due and system chugs when I try to run just a few programs! THANKS!

P.S. the system did this before, but the beeps came very very seldomly, like once every couple days, and only beeps once.

A:HELP mobo beeps + lags

Open up the side and see if all the fans are working and clean. If any of them are clogged with dust, get a can of compressed air and blow it out. Just to get rid of any possibility of it being a low fan rpm or overheating alarm.

If you have a spare stick of ram, you may want to try replacing the current stick in the PC.

Hi guys,this is 2nd or 3rd post on this forum so if here its the wrong place please notice me.So here is my story 2 months ago i built desktop system(not the greatest but...) which is:
Mobo:Foxconn A6vmx
CPU:AMD Phenom x3 8600
GPU:ATI Radeon R7 240 1GB GDDR5
2x2GB Ram 800 MHz
A friend gave me this motherboard and i decided to make something with it.The problem with it was that the pc wasnt shutting down.Everytime i wanted to turn off the pc i had to unplug the power cord or to switch off from the psu's button.I did this untill my hard broke,about one week ago.Now the problem is that when i try to start my pc The cpu fan and one 12 cm fan are spinning but i get black screen.Also the gpu fan is spinning for 1-2 seconds then stops.I borrowed a GT440 (2GB GDDR3) from a friend to see if the gpu is faulty but same black screen,but that gpu's fan is totally spinning.I took an older cpu and tried it same problem,also tried with one stick of ram same problem.Also when i start the pc without ram i dont get that beep noise from the speaker so i think the Mobo might be the problem here.Tried my psu on another pc to see if its working properly and it is,I took another psu to try it on my pc but same black screen.
Tried also clear the cmos same problem.
Now im asking you guys if the mobo is the real problem or could be something else.And if you could tell me what else i could try,im all ears. Sorry for bad english tho.

A:Fans are spinning but no display.Mobo faulty?

Hello Poli I know you have checked out the PSU but please do this in my little ditty and post back a pic of the PSU voltage rails
Using HW Info
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
See this for the rail voltage info
http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

Use PART A: and as an option you can use a digital multimeter and test the volts on the 24 pin board plug see this for the colour codes http... Read more

My old cpu melted off the mobo due to heat and continuous usage
where I live.

I purchased a new case with a PSU, new FIC KT-748 mobo,
and want to use a used Athlon 1.2 cpu.

FIC will not respond to support email and their support # is always busy.

I think I connected the front panel switches properly because
the system does respond when I press the Power switch.
So I have a new mobo, PSU, and case; used RAM and cpu.
The cpu came off a HP that had a damaged mobo, so I thought
the cpu may still be good. The RAM came out of my old melted
system (I also have another stick in case).

When I press the power switch, the case fans, psu fan, and the
cpu fan are working. I just get nothing on the screen, not even BIOS.
I reset the CMOS. I get no beeps after letting this run a few minutes.

I'm starting to think the cpu has gone bad, but I 'm not sure.
If I need to, I can buy another cpu easily.

Thanks in advance for your response......

A:New mobo, used CPU - Fans work, but no Video or BIOS

Have you tried the memory in a different slot? Swapped the memory with the other stick? There are many variables that can come into play. And you are correct it still may be a bad CPU. But take all added parts out and see if you get any beeps with just the CPU in place.

so I've assembled my gaming pc, but I'm worried I damaged my mobo with static shock. I felt a shock yesterday while building the pc when I touched the mobo, and now this is hapenning. I plug it in, try to start it, and the motherboard light flashes once, the fans twitch, and then stop. The case light is on but no fans are spinning and the motherboard light is off. Any suggestions on the problem or in general would be greatly appreciated.

First off comp specs:
2.8ghz intel (Recently replaced after being "burnt out")
MSI 865PE NEO2-LS (Replaced twice)
Radeon x800 pro 256mb
Memorex combo ultra-speed recorder cd-rw/dvd-rom drive.

I think thats all the info needed for this problem, if more is required just ask for it.

Now for a little history:
First Mobo: Incorrectly flashed bios, had it replaced via warranty
Second Mobo: Chip FRIED(like, black) taking the processor with it(or so the repair guy said)
both replaced via warranty

Now i have a problem with my new mobo(or so i believe) and no trust in the repair guy.
I get a series of beeps when i start my computer: 2 fast short PAUSE 1 short
Tells me to press F1 to resume then seemingly works normally.
Only one problem with that: My mobo doesnt seem to be detecting my CD drives(tried 2 different ones, neither showed up in My Computer/Device manager/read CD's)
Right now these drives show up in place of the one i have connected:
2x Generic DVD-ROM SCSI CdRom Device
Obviously these dont work.
I have replaced the IDE cable to no avail, tried to find drivers for the memorex to no avail, rebooted several times simply trying different things to get the computer to recognize the drive to no avail. It is on master and on a single seperate IDE cable as was its working predecessor.
*Note* the other drive(model GCC-4481B from an EMACHINE family computer and grafted onto mine) worked pefectly until i had my most recent mobo blowout and replacement.

Hi my name is chris and im having problems with my new rig the computer is as fallows

Mobo - m2n32-sli deluxe by ASUS
ram - 2 gigs of crucial ballistix
Video - 8800gt OC by BFG

now my problem is that when the computer is all the way shut down and i hit the power button to turn it on it powers up but during the normal boot procces wich does still finish im getting a series of 3quick beeps ive looked this up on the bios error lists and they say its a memory problem or somthin like that... so anyways it continues to beep untill about the first Windows screen that displays during boot and once it stops it doesnt come back untill the steps are repeated but as you can see the computer still works fine ive played on some high graphic 3d games for a decent ammount of hours no problem nor crashes or anything of that sort but the beep on boot is extremly annoying and i dont want it to turn out being somthing thats gonna fry my computer in the long run either so any help are ideas would be much needed :) thanks again.

What ive tryed so far:
1. reseated both sticks of ram
2. turned off quick boot and let it do a full system test (no errors found)

Mobo making error noise while using my HTPC every so often. So far, I noticed it when:
Playing Deus Ex (low settings 1024 tops)
Watching TV through WMC (HD Homerun Prime)

Here's a vid I uploaded to YT when watching TV through WMC:

I doubt it's an overheating issue, in this particular case, the PC was on for 20 minutes and is well ventilated, I leave it in the open.

Deus Ex was the only game I tried, and so far, only watched tv 1 time, all other times when using pc for normal functions (surfing, videos, music) no problems. The next day when I booted up the PC to watch TV, no beeping noise.

A:MOBO beeps when doing something graphics intensive

-Loose items: could be a loose cable causing vibrations or hitting a fan in the case? or maybe the motherboard is loose? How do you have it positioned? Sitting up or laying flat?

-Can you hone in on where the noise is coming from? Hard drive? additional case fans? graphics card fan? or just the MOBO in general?

-I wouldnt leave the case open 100% of the time this will allow dust and other stuff to float in and could cause damage. Do you have any cats or dogs? Could end up with a toasty critter.

Earlier today I get back to my computer and it looked like it was frozen, because the mouse and keyboard didn't work. So I rebooted and it got into Windows normally, but the kb/m became unresponsive again. And I new it wasn't the system that was frozen because the connectivity indicator was animating. And each time I booted the kb/m became unresponsive at a predetermined time, whether I was in the Windows sign in screen, the BIOS setup, or running on the windows installation CD.

And in between these times it seemed like it had trouble starting up. Sometimes when I pressed the power button the fan would just give a little wheeze and nothing would happen. Later, pressing the power button did nothing at all.

Then one time I tried unplugging and replugging in the PSU it started acting goofy. Now whenever it's plugged in to the outlet, it emits this high pitched sound. And if it's plugged in to the mother board, its own fan and the CPU fan automatically start going, even though the computer isn't on.
What do you suppose might be wrong with them?

Motherboard: Chaintech VNF3-250
PSU: Thermaltake Purepower HPC-420-302 DF

A:Did my mobo or PSU bite the dust? kb/m lock, no boot, fans run when of


Your in a chicken & egg place here, but I would suggest the power supply first place to start as that is the cheepest to investigate.

A power supply of only 420W does seem a little low though?

So I was watching a video from my 'Nix box last week while running some pretty heavy CPU intensive apps and the computer froze on me twice, My CPU never freezes so I thought that it was odd but the PSU and GPU were running a little hot so I thought I would tone down the usage as I had just installed some new cooling fans a day before and a new CPU about a month earlier. Then the computer shut down and wouldn't start back up. I replaced the PSU originally thinking that since it had been running hot maybe it just died. Installed and no power no fans nothing. Replaced the mobo with the same results, I'm at a loss right now as to what the problem could be. I even switched out the push button in case that burned out somehow and nothing. Any ideas where to go from here?

Update: just an update after posting I found the POST walkthrough and followed it step by step and still nothing. Would a bad CPU cause there to be no power through the whole board? I replaced the CPU fan as well to be sure and I can't seem to find any other possibility.

A:Computer shut down, no reason, no fans spin, new PSU and mobo

Yes a bad CPU would cause the board not to function, but bad CPU's are very rare unless they are damaged by handling or installing. What type of CPU is it? The socket type can matter for damage

So I have just had to swap my motherboard after a power surge got hold of my last one.

Now my graphics cards are randomly putting green dots all over some web pages & programs.

I've seen blue and red ones too on the odd occasion. I do remember having a similar issue with just one monitor a while back, and as far as I can remember I just kept fiddling with the cables. That isn't working this time though.. is it just a case of upgrading drivers, because of the new mobo?

Also I've chosen not to put my crossfire cables on, simply because I was not using crossfire any more.. a little silly but would that contribute?

when i go to turn my computer on 4 solid Red led light's are on. im wondering if this is just a simple bios chip change or if my cpu mobo and ram are fried if anyone has experienced this problem before with a nf4 lanparty ultra-d mobo and fixed the problem knows. if you could get back to me asap would be nice

A:4 led light's on mobo

Just hanging at pre-post?
Some NF4s had a occasional cold boot issue.

If you've made any recent changes/upgrades check that all cables are securely connected.

Sometimes a hard CMOS reset can help:
Remove the power from the PSU, and power up to drain off any excess power
Remove all but 1 stick of RAM
Remove the battery
Move the clear CMOS jumper to the clear position.. wait about 10 minutes
Replace the battery
Move the jumper back to its original position.

Now try to power up again. if you can post go straight to bios and "rest optimised defaults"

The lights mean:
4 LEDs on = Power applied, checking CPU
3 LEDs on = CPU has been detected OK, checking RAM
2 LEDs on = RAM has been detected OK, checking VGA
1 LED on = VGA has been detected OK, entering BIOS
0 LEDs on = System has booted to the Operating System

Have you tried clearing CMOS?

I have a Dell Optiplex GX150 and does anyone know if this PC case can fit a differant mobo inside cause iv'e heard that I may need to change the casing if i wanted a new mobo?

A:PC case + Mobo

Even if it did fit, which it probable won't, you would need a new power supply because not Dell powersupplies are not always standard ATX and are usually unpowered. Also it appears this case offers no expandability due to its extreme small size which is also terrible for cooling.

A new case with powersupply can be bought starting at arounf $50 and up that have a decent powersupply and are fully ATX standard.

A friend of mine bought a new case for his comp.
His mobo is an AT his ps is now an ATX he bought the adapter,
but he still can't get the beast to fire up.
Can anyone offer any help
Thanks ,

A:New case old mobo

You are going to have to be more specific as we will try to find a solution for you. This could be anything.. from a failing processor to an improperly inserted cable... so it is really hard to pinpoint the issue from the information posted.

It doesn't boot up.. to what extent? (Do the fans spin? Is there power, led lights, hard drive spin etc.)

One suggestion is to double check everything... and make sure everything is properly mounted.

Hi guys, hows everyone, hm dumb question but i have to know, recently bought a new mobo+cpu combo PC CHIPS M-811LU V3.1C ATX Motherboard/CPU Set - Retail, from newegg, since my emach fried out. Not sure whats wrong with it.
Works nice to far. Rigged up without case.
Building pc from spare parts i have laying. But problem being is, that i have no cases that fit. Doesnt fit in emachine t1400(athlon1600 sdram) case ether. Anyway im on a tight on money. It says standard atx form factor .What kind of case would this use, it says atx and yet my emachines case would not fit it says atx. Mobo measures 305mm x 190mm. Wanted to buy another of the same mobo soon. Nice deal they have i think.
Was looking at newegg for cases, mainly the cheap ones they had from 25-60$
Would anyone of those work that they have.
