I already had windows 7 installed on my PC . but when I insalled a new OS , I discovered everything was working fine but the graphics of my games got ruined . game is working perfectly fine but when i start the game the graphics looks really bad..I used to play that game in Windows 7 and it used to work perfectly fine..but i don't know that happened suddenly ..Everything is working fine but all games of mine are having bad graphics like counter strike condition zero and GTA san andreas and I decided to go back to windows 7 . I did that too but iam still suffering from the same issue. please help me
