I recently bought a radeon x850xt, and after installing it, it was working fine. Until a few days ago when pixel's and ploy's slowly started to glitch, now a few days later I cant run any 3d app at all. 2d still works fine, I have not overclocked or modded the card, ive Installed about a hundred new drivers, and my power supply is 550w. still i cant get it to run 3d games any help please???
