Hey, I'm having a lot of issues when trying to run most games on Windows 7. I have an ATI HD Radeon 5970 and whenever I open, say, Team Fortress 2, it will get past the first few screens and then when I try to actually play it will freeze up then give me a BSOD saying the error is 0x0000007E. I've tried uninstalling the latest drivers and going back to an older one, but it's the same issue. I've got no idea how to solve this. Any ideas?
