I recently reformatted/reinstalled my windows xp --- about 4 months ago. When I did no games would work. I open up a game (CS:S, RO, Oblivion) and it will make the screen turn all black as if it is loading. After one or two seconds of black the game minimizes and maximizes itself (still only a black screen) and after it maximizes the game closes/process ends. This has been really annoying since i can not do any type of gaming. I do have a onboard graphics card but It is not recognized on the computer.I have a Radeon x700 currently installed in my AGP slot. The same problem occurs if the card is in the computer or not. I have tried taking the card out and the computer is the same with out without it. The card as far as I know is not fried. Any suggestions?
