I have a 970 xtream and was overclocking it with guru 2 and heaven benchmark open. I was tweaking it till it was stable but when i went to hop on cs where i was getting over 400fps on a 144hz monitor i was suddenly getting 20fps. The heaven benchmark score was lower and other games were running like trash. Ive tried reinstalling guru 2 and resetting all the profiles to default but nothing has worked.

Im not sure what i overclocked the gpu to because after the performance drop i reset it to default instantly.(i was using guru 2)
I did delete guru as well and restarted but still nothing.
