Hey, I don't know what the problem can be, so I need some advices on what to do. Basically every game I open will freeze a few secounds after it starts (not the menu, but the real game in the levels). It can then start again and run as normal for 2-8 secounds before it freezes again. I dont know what to do, or what it could be. I have Radeon XFX 5870, 4 gb ram, phenom 965 IIx4.
