I have a Sapphire rhadeon 7850. It can run almost any game on highest quality. So I purchased Crysis the original off steam and attempted to run it at Very high settings. After about 10 mins the graphics card crashed. So I had to downgrade it to High. After about a day playing on high it begun to crash on high as well. I now can only run it on medium. Today it crashed while I was playing Planetside2 and it has never don't that before. And just a few minutes ago it crashed while I was playing saints row 3. I believe I have the latest drivers and I don't know exactly what to do in the amd catalyst. Thanks for taking the time to read this. Any suggestions would be helpfull.
