Windows won't let me run anything in full screen

Hopefully this'll be easy to understand.

My laptop won't let me run anything in full screen.
Virtual PC will say that it can't switch to full screen mode and to check if the virtual machine's resolution is any higher than the host system WHICH ISN'T! I also have a game which is full-screen only, and if I try to run it, it'll say "The specified resolution is not supported by your video card."
WHAT DOES THIS MEAN? Do I need to uninstall something or change a setting? I really don't know what it is. Can anyone tell me? Please?
