When I uninstalled Iomega HotBurn software, after a reboot Windows
reinstalled about 20 drivers. The one for the video card or montior is
not correct. I am stuck at 16 colors with a resolution of 640x480.

I tried the steps in Jeff Richrard's reply above, and Windows said I
already had the best driver. I know the file is in my system or on the
Windows 98 SE CD, because the display was working just earlier today.

My monitor is a KDS SVGA 15", and my video card is an S3

Thank you,
Daniel
