I purchased a Radeon HD 7750 about three months ago and has been working perfectly, playing games at 1080p with no issues. However, about a week ago when I try to boot any game the picture becomes very choppy and I have lowered the resolution and it has not fixed the issue. I have checked for the lastest drivers and updated the microsoft framework to 4.5 but it still continues. If I go through AMD catalyst and update, everything will be fine again, but only temporarily.
