Hello.I got a problem with my PC.I bought a new GPU so i can play my games w/o stuttering or lagging but now I have an issue,my PC keeps freezing and/or shutting down then turning back on at times whilst playing some games(not all).So the question is,is it my GPU that's causing the issues or is it my GPU+OC'ed CPU.I'v stress tested it with prime for 6 hrs,max cpu temp was 55 and core 39,there were no errors.I'v never had these issues with my former GPU Gainward GTX 650 2gb.Also the GPU temp reaches about 75C so i manually adjusted the fans to 47% thats about 1600rpm,usualy it reaches 1300rpm at 75C on auto.
