I have vista/64 and am using foxconns 8800gts 640 mb card. playing online or single player Ive noticed while raising the players head up and down I see a horizontal distortion line accross the whole screen. Am wondering if its the card or vista?

looks like a driver issue, which driver have you got latest whql or beta (try beta maybe it'll fix the issue). also make sure you got the latest patch for the game that you're having issues with.
P.S.: if you're a gamer why did you get vista x64, it's to early (driver and support wise) to game in vista. if you can, dual boot xp and play your games in xp.
I tried the drivers from uguru but they locked up the computer. I play hl2 deathmatch online which has no patch. They just do steam updates. Also, its not on every game, just some which makes me think its the game itself. Oh, I have the latest drivers from nvidia
