Hello, me again. it seems my PC woes haven't ended. last month i reported on my PC randomly resetting/restarting itself while playing Steam games. i thought it was the RAM which it probably was with one bad stick, so i promptly set about buying 4Gb to place the 2Gb i had. all seemed fine until it started rebooting again, with the 4Gb. now either i'm very unlucky with RAM or it's something else. i thought it might be the gfx card overheating so i used Rivatuner to crank up the percentage to 80% (it defaulted to 40% before RT). same problem however. now i'm guessing it's one of two things: either the PSU is failing or the NB is getting too hot. i was trying to play another Steam game and the PC just turned itself off completely; my heart skipped a beat thinking the PSU had blown, but the keyboard LED was still on and mobo LED was on too. i've turned it back on and it's working all normal. i've been using Speedfan 4.40 to find out the temps inside and see if i can adjust the fan speeds. but i've noticed something odd: +5V and +12V are normal but my -12V is reading -16.97V and my -5V is -8.78V. is this a bad sign that the PSU shuts itself off at load that its failing? it's an OCZ 1010W PSU, i can't remember the specific model something like GamerXtreme. or could it be the NB that's getting too hot and it's shutting the PC down? i'd read somewhere else that the NB needs to be cooled, well i have an Asus P5N-E SLI which uses passive cooling for the NB/SB and VRMs. any expert opinions/suggestions as to what's happening?
