Hey y'all.

Having just built my pc with some new bits, new motherboard and hard
drive i'm having a problem. My PC keeps restarting at random
intervals, while playing games and also when just general activity. It
doesn't seem to be heating problems, the CPU is running at around 30c
and the system temp is about 35c. All fans are running, it even
restarts with the case open. I've tried swapping my RAM to see if one
of the sticks was faulty but still does it. I don't even get a bsod, i
have the 'automatically restart' option unchecked too. Power supply is
ample i believe, at 550w so i don't think it's a power problem as i
didn't have this problem in my old build.

The motherboard is a Gigabyte GA-P31-DS3L. Graphics card is a 8800gt
512mb pci-e. Sata hard drive @ 250gb.
XP Home SP3.
core 2 duo 6400.

I don't have a cd burner or floppy drive so i can't use memtest. The
event viewer doesn't show any errors either.

Any one have any suggestions?

Cheers.

While a 550W should be more than adequate for this, many cheaper PSUs
are not actually capable of anything like their quoted rating. I have
had a similar problem to this in the past with one of the PCs I was
tasked to support at work. It turned out to be the PSU on its way out.
I am not saying that this IS the problem, but it might be.

It is a hiper brand of PSU, so i should be ok.

The cheapest option to start with would be to buy a floppy drive (£6)
and run Memtest!

Yep, looks like i'll have to to rule memory out.

What program are you using to measure the CPU temperature? Different
programs will give different values. I have found CoreTemp to be one of
the most reliable.

RealTemp, Rivertuner and coretemp, all showing around 30 - 40c.

Seems like you have a generic newer combination. I seriously doubt you
need a bios update. I assume you have CDrom and USB ports. So you
could buy USB stick to write boot diagnostic programs.

I would start at the beginning:

Verify the video, cpu, cpu fan and memory are completely and correctly
installed.

Verify the motherboard is installed correctly, safe from static charges

Completely disconnect the SATA HD and CDrom from the M/B and PSU.

Then boot the PC for a couple of hours to make sure the components are
working.

If you burned a USB boot diagnostic, run the diagnostics, watch the cpu
and gpu temps.

If the PC doesn't crash its probably not hardware but the Windows
install, reconnect the HD and CDrom. Boot to Windows Safe Mode, run a
registry cleaner and defrag the Hd.
