I NEED HELP! When I install nVidia or Leadtek drivers, I cannot change resolution (it will go blank) and I cannot run any video media file (it will freeze). WHY?! If I leave out the drivers, I can change resolution and run DVD's, but it does not look very good and is choppy (no games will play either). What is wrong? I got the update GTA3 told me to get, and it did fix the problem in GTA3. However, I still cannot change resolutions or run video media. This is a serious problem, and I need help FAST. I have to get this PC ready by tomorrow morning. Please respond if you know anything at all about this. Any theories are welcome too. Thanks in advance.
