troubleshooting friend's rig.

[Negative Decibel]

So, a good friend of mine is having computer problems.
Q6600 (no oc)
GA-EP45-UD3P
BFG Tech ES SERIES ES-800 800W

Computer randomly shuts off. No bsod, no locking up, not rebooting; just shuts off.

My first thought was overheating. had him run prime95; temps were fine. Infact, had him run it all night long. No problems. Played CODMW2 for a few hours, shut off 4 times during the game.

Checked out temps on GPU; they were ok.
Ran Memtest overnight; no problems.

So, I'm begining to think that it's the PSU... possibly the mobo. Does this sound right? I'm going to bring him a spare PSU for testing tomorrow. Is there anything I'm overlooking so far?

Try stress testing the GPU...if it shuts off during Furmark you'll know its the GPU or the power supply.
I had similar symptoms when my 470's were tripping the overcurrent on my power supply.

Ok. have not tried furmark... thanks.

How did you test with Memtest? Each stick individually or all at the same time?

did both sticks overnight. because there were no problems, I did not think it was necessary to test individual sticks.

Occasionally. you'll have situations/cases where only one stick is bad but Memtest can't detect it on account of a second RAM stick being installed in the system.

Try testing each RAM individually if the PSU swap, Furmark test, or GPU swap doesn't show an issue.
