[INDENT=3] I'm having a problem that is very hard to narrow down. My computer randomly shuts off, at first it happened only while into a game for 20 min. to 1 hour, but it's happened just in windows as well (though I can leave the computer on all night doing nothing no problem.
I've ruled out video card over heating.
My system is:
AMD PHENOM II X6 1090T
Asus M5A88-V EvO - motherboard
8 gigs kingston ram
Sapphire AMD Radeon 6770 5DDR 1 Gig card
Coolermaster extreme power plus 550W
After a lot of benchmark tests that proved inconclusive, I swapped out the PSU for an identical one (unfortunately the only one available to me). Same issue persisted.
So I thought it was the video card, so I put an old video card in, ASUS EAH 4850. I played swtor for about 40 minutes then it shut down, not overheated.
So is this PSU just bad all around and should I test with a brand new one? Or could it be the motherboard or CPU?
I ran a mem test and that was fine. What other tests could I do to diagnose?
Thank you in advance
