Hello,
I'm new to overclocking. I just bought a new pc.not that high end. intel i3 3.2GHz, ATI radeon HD 5450 1GB and 2GB ram. Overclocked the gpu using AMD Overdrive. temperature within 60-65C when loaded and 50-60 idle. Started playing witcher 2 at ultra settings. works fine. no probs. But suddenly the screen started to freeze every 2 hours or so and the blacks out. Then starts up again in a minute showing the desktop and then the game reverts to where it left off as if nothing happened! This didn't happen when I played W2 without OC. So is this related to that? I'm at a loss.
