no video, video card not working i was playing Knight Online with my nVidia geforce mx mx 400, when suddenly i started noticing some bad graphics, so i exited the game. when it showed my desktop, it was at 800x600 ( i usually have it a 1152x864) and when i tried to change the resolution back to where it used to be, i got a messege saying that the card was made for an older version of windows. thing is, i havent done any updates lately, and i had run the game perfectly after the service pack2 came out. now i cant see anything when i plug my monitor to that video card. thnx in advance ps. i tried the video card on another pc running on windows xp but without the latest updates and the card works perfectly fine.
