I have never had an issue. Sometimes it's an operator problem, not hardware. :smile:
There's an issue with Radeon cards and Windows 7, atleast that's what I think it is. My home computer does it occasionally, and my work computer does too. Mine will sometimes recover on it's own talking about how the graphics driver stopped responding, and it's definitely not a heat issue, I have a temp monitor running all the time on my home PC. If you google "Radeon driver has stopped responding" you'll find a laundry list of forum posts of people having the same issue.
The radeon driver attempts to correct the issue, but if it can't it blue screens.
