I'm having a number of issues running newer games on my machine. For example, I am currently trying to play Bioshock Infinite, and the game runs absolutely fine on the highest settings for 2 or 3 minutes, before the screen displays a solid colour (Usually dependent on what area I'm playing through, for example, there are a few grey coloured statues around, when it freezes the screen turns grey) When the freezes occur the sound often continues without error, but the system does not seem to respond to alt tab, ctrl + alt + Del, or anything else. I suspect since the sound is still running, that it is simply the graphics output that has turned unresponsive. I'm guessing that some kind of driver conflict or direct x problem is causing this. I tried turning the settings on Bioshock Infinite to the minimum (To take away direct x 11 effects etc), and updated my drivers to the latest versions as far as I can tell, but the problem persists. I guess my question is, can anyone either shed some light on this, or advise me on how to completely clear and reinstall the drivers/directx that might be causing the problem? I also have the same issue with crysis 3 in about the same time frame, but it happens very very rarely with TF2 (It has been weeks since it has had problems with TF2). Funnily enough, Dead Space 3 had no issues whatsoever. System specs are: Asus PBZ77-m ATI Radeon HD7850 Windows 7 Pro 64 bit Intel i5 3570k 3.40Ghz 8GB Ram Help appreciated.
