I just bought a brand new XFX 5850 in September of 2010 and for a month or two it worked fine. All of a sudden my computer started crashing to a green or grey screen with pinstripes and then i have to restart or just turn off my computer. This occurs not only when I try to play games but also when i try to surf the net. I have tried several different Drivers including 10.8, 10.12, and 10.11. Every time i try one i uninstall EVERYTHING completely and then install the new drivers and it still does not fix it. I had it working for about a week but then after that it's gone back to crashing again. If anyone has any ideas on what i can do to fix this it would be greatly appreciated. I installed the card correctly and it has not been damaged. I have a 550W BFG PSU as well, if that helps.
Thanks for any help
