Ok so recently I've been having problems with my PC crashing on start up and whilst playing hardware intensive games (CoD 4, GTA 4 etc.). I've run BurnInTest to see if I could stress my system but it passed with no errors so now I'm out of ideas as to how to diagnose the problem.

An amatuer guess by me would be a problem with 1 of the following:
  • the CPU over heating (this would make sense in both cases as it may overheat when playing the games and during start up before the case temperature is sufficiently cooled)
  • the power supply cutting out (again would perhaps make sense in both instances)
  • the GPU having a broken section only relied on by graphics intensive games (though it wouldn't explain the start up crash so perhaps they're unrelated)
  • a problem with the motherboard - perhaps a minor crack somewhere?

Anyway as you can tell I'm a novice with computers, though I have built a few from scratch including this one. The current PC worked fine with all the same components not long ago and has had a fresh OS installed (XP to W7) so I don't think it's driver related and runs fine whilst left on and not doing anything particularly hardware intensive.

I'm hoping it's a problem with the PSU as this would be the cheapest to replace but if anyone knows any tools to diagnose the problem it would be much appreciated.

Thanks for any help,
HLS

p.s. sorry if this is in the wrong section

List the brands and models of the Motherboard, CPU, PSU, Ram & Video card.
Have a look in the Bios on the PC health page for the CPU temp, and the voltages 12v, 5v, 3.3v.

CPU: Intel P4 socket 775 3.0GHz
PSU: 450W 350V
GPU: BFGTech 8800GTS 640mb PCI-e
RAM: Corsair DDR2 PC5400 1gb x2
Motherboard: Intel D945GNT

This is a spare parts build which I'm progressively upgrading which is why it's so miss matched but it has been running fine for months and only recently had problems. To expand on the problem whilst starting up for the first time in the morning it will crash ~3 times on average and whilst playing hardware intensive games but aside from that will run perfectly.

I'm hoping these are related problems and solvable either by a replacement PSU (cheap) or CPU (requires upgrade anyway). Whilst we're on that subject would anyone be able to tell me if my motherboard would support a quad or dual core please?

Hope that's all the info you require and thanks for any help in advance,
HLS

Forgot that last bit sorry, here they are:
CPU temp immediatly after a crash: 61c (prescott cpu so I've read they naturally run a bit hot)
v12: 11.750v
v5: 5.084v
v3.3: 3.302/319v
v1.5: 1.542v
vCCP: 1.300v

sounds like the cpu is reaching it's temp limit and shutting down IMO

My System

Send a message via MSN to linderman

I agree on the cpu temp / 61C while in the bios is way too hot .......should not be more than 45C


i also am leary of the 12volt reading while in the bios ...........11.75 is too low for a system doing nothing!

I agree the CPU is a tad warm and the 12v is near the 11.7v mark where we've seen video issues.
I would start with the PSU.

Thanks for your help everyone! Following your advice I'm going to be buying a new power supply - I've gone for the Corsair 650-TX -650 watt recommended in the power supply thread and a new CPU fan. It will probably take around 5 days for delivery so I'll let you know how it goes when it's all installed.

Thanks again,
HLS

Both installed and it's running perfectly now. No crashes during start up or whilst playing games.

Thanks again everyone!
