My windows xp stuffed up. I was trying to play NFS underground ebfore and suddenly the images went up-side-down so i exit the game and returned to windows. However, all of the colour of the windows are gone. I only had 4 colours left and I was stucked in 640x480 mode. I've rebooted my computer but no luck. I entered safe mode but everything including the colour and resolutions works fine. I am sure that is not caused by my monitor. I am trying to reinstall my display card driver. I googled it but so far can't find anything related to it. Anyone have any ideas what is going on?
