I recently (1 month ago maybe) bought a new HIS 7750 (iCooler version) and it worked fine for maybe the 1st week. Then I would get the occasional blue screen, and now when i start my PC it freezes and get a blue after around 30 sec of running. when i look in device manager my old video card is still listed there (radeon 3200) even thought i uninstalled it completely before putting in the new one. I tried disabling the old one, uninstalling with device manager, uninstalling the 7750 and reloading the drivers. That fixed it for about 2 days, and now i have the same problem again. .. .
