ATI is literally the worst with BC2. Google ATI Crash to Desktop. There are about two hundred programs you can't have running on your computer while you play BC2 or it hardlocks completely, among them pretty much every overclocking and system utility out there.
To this day, there are hundreds of poor schmucks out there who can't understand why they can't play BC2 for more than 10 minutes at a time without realizing it's because they installed MSI Afterburner, ATI Tool, etc.
I don't run extra stuff besides fraps when gaming. So I don't see what the issue is. It's also really easy to determine where the problem lies with some simple troubleshooting. Especially in that case.
Doesn't matter anyway because BC2 will be dead soon.
