I have an XFX Radeon 7970 HD black edition, and I think the driver for it is crashing over and over. Basically, I'll be doing something (doesn't really matter what, crashes as often while on firefox as it does when I'm doing anything else), and the screen will change into a dull green or blue, with vertical bars of a similar colour on it, working fine on restart. I can still transmit and receive sounds through skype. It started at the beginning of this week, shortly after I got Dota 2, and has been happening on and off since then. Sometimes it won't crash at all for a day, sometimes it'll crash twice in 5 minutes.
I've had the card for a few months now, with no other problems. So far I've tried getting MSI afterburner and changing one of the config settings, and downloading new drivers, neither of which have worked. Anyone else had this problem, and any suggestions to fix it?
Edit: I think something slightly different may be happening now, because I just had the screen go completely black, then a couple of minutes after restart, it went completely white, neither of which have happened before. Both times this happened while on firefox.
