Strange Overclocking ?

[FuriousPanda]

(first time posting)
Hey, I tried overclocking my gpu (palit 980ti) and something weird keeps happening. I use my benchmarks and such while overclocking and the thing works like a charm. Until I put a game on that is. I have 2 monitors, a 1080p 60hz and a 1440p 150 hz. I always benchmark on the 1440p one. When in game the second screen randomly turns green-ish and stops working, after a while, or if I alt-tab the whole pc freezes and i have to restart. If i remove the oc everything goes back to normal though. What could be going on?
Thank you for your time

sounds like your overclock isn't quite stable, dial it back until the symptoms disappear

I tried to do what you said, but it was unstable even at +10 core +20 mem (did that just to test i know it wouldn't make a difference)

might be a driver issue then, get ddu (display driver uninstaller) and remove the graphics drivers then reinstall. Hope it helps

problem seems persistent through updates, would uninstalling work ?

well, it won't hurt anything at least. The only other suggestion I have is to trigger an event then open event viewer, under windows logs->system and look for an error around the time you triggered it. If it created an error log it may have some helpful information. Or you may have got a silicon lottery dud and you just have to leave it at stock settings
