Do you also happen to have black screens during your web usage? I have black screen using web browser, mostly when doing graphical things like playing video. I also have this problem sporadically when using rendering programs, graphical programs. The worst thing arguably is that it happens at random. AMD is battling this issue and it looks like what they fix and patch, just resurface in another patch.
No, never happened during web usage, not even during benchmarks, video rendering or anything else, only when playing games.And when it happens, if I shut down PC using the power button, next boot is really long, like 3 or 4 minutes.
run dxdiag and look for .txt info .
maybe some application is causing a conflict
something like this:
or attach here dxdiag.txt file from dxdiag
