So I just upgraded my graphics card from a Gtx 760 to a Gtx 1070 ftw and now when I play games for awhile my screen will go black, but I can still hear sound and talk to people I already planned on upgrading my psu, which is 500w to a 600w could that be the problem. It isnt heat I've checked and it doesn't go over 55 degrees under load.
PC specs

Gpu: Gtx 1070 ftw
