Lately my computer have been crashing quiet a lot. when it starts i check what crashed my computer. the system says it was a "kernel power" but it is only supposed to come when the power supply isn't enough so i thought it was the ram, so i tested all the memorys with memtest+ and with my motherboard memtester. no sign from them that they were broke. so i tried again and it crashed later on. again i start to check it. it says again "kernel power". so i thought it was voltage spikes that were crashing my pc. so now i went and orderd an UPS unit 650 watts. plugged it in and bam. no crash for 3 weeks. then i installed farcry 3 and played it for 20 min, Crash again. so now i have given up on the trouble shooting. please help...

when my computer uses more than 650 watts, the UPS starts alarming. have only happend 2-4 times.

it crashes when i play farcry 3, saints row 3 and crysis (any) and some other applications.

it freezes the computer and then it lags the sound so it sounds like an annoying loop (obvious)

i will repost my specification of my computer maybe you can help me or explain what i can do to find the problem...

sorry if i post this in the wrong tab.
