Basically I was overclocking my GPU and my computer crashed (white screen) I was maintaining relatively stable overclock on my GTX 970 Direct CU ll when playing a game it crashed so after restarting I thought I'd benchmark my GPU again at the stable clock speed on 3D mark my previous results were 11512+ on firestrike but now only getting 6000 with low FPS in the tests. physics seem the same but fps checks and combined all low any ideas broke my GPU?
