Sup!
so after a clean install games will hang (freeze) for 1-2 seconds, before going back to normal. It affects all game.
For example I can play lol on high at 60fps. I don't drop frames, I just freeze before returning back to normal.

The process tab when playing games.

installed 32 bit windows 7, but i'm pretty sure It was running 64 bit, and they both handle ram differently, could this be the problem?

Thanks in advance!.
