Thanks for the help guys. I will try the tests later tonight. Now, I forgot to mention, when I say 'reboot/restarts', I mean, it does that before it even gets to the F.E.A.R. menu, same with FarCry. Call of Duty still crashes like it did before too. So, as usual, FarCry isnt secure anymore either, so FarCry, F.E.A.R., both restart before menus and Call of Duty plays game within 10 seconds then locks up. Its not a heat issue, my watercooled temps idle at 36 and after playing some Doom 3, its around 40's. I have 2 gigs of Ram, so I dont know if its a Ram issue, but I will try the tests. Im seriously thinking its not my PSU. Its either my video card, or motherboard are my best guesses. Im going to switch video cards tomorrow probably and test that.
