Anyone help me plzz. I'm using dell laptop and recently I changed my windows again to Windows7 ultimate(before also used the same) as some windows files were deleted due to some reason.now after installing the same I can't play any games. If I install something like blur it shows that error but nothing.in assassin creed 3 it shows that ac3sp. exe has stopped working. I'm having Intel hd 3000 and 32bit os with 4gb ram. And moreover after changing windows if I see the properties of video card it showings n/a or unknown. Moreover if I goes to games like chess titans it shows messages that hardware acceleration is disabled or it is not supported by your video card and the game is now very slow. So now can't play anything. So someone help me. Not very expensive way
