I'm having this problem with the card, i guess when under "stress" (and i assume this because it only happens when gaming) the pc just randomly shuts off. I have to plug it out and in again for it to power up again. Could you help me out? (Sorry if my english isn't that good.

My pc specs are:
Cpu amd fx 8120
8gb ram kingston
asus m5a88 m
zotac 660 ti (regular)
550w sentey ERP

I had an old power cord instead of the new one, i changed it, cleared pc from malware (over 20), adjusted the fans to personal because automatic wouldn't go over 50% at full charge and i ran furmark and prime 95 at full load in extreme settings in order to stress the whole pc at 100%, and the pc didn't shut down after 15m and i tried other settings just in case for 5m (far cry 3 would shut it in just a few minutes) so i guess something went well... either way if you have some suggestions... i'll take them
