Hello Guys, i recently bought a HD 7850 Sapphire OC edition and i've been having trouble with crashes with grey, or blue/pink colors and vertical lines down the screen, it's not overheating either, at idle it's 37 degrees, and around 70c at it's highest and it only seems to happen when surfing the web or watching a video on youtube and figured it was a Flash issue so uninstalled that, and Java disable hardware accleration and uninstalled AMD drivers completely as in removing registry and software completely and reinstalling. So to no avaid it crashes with a 0x124 hal.dll address so it seems i made it worse with uninstalling drivers. And i don't know the stock values for the 7850 to use on CCC. Any advice would be appreicated ect.
