What do you mean you don't have a videocard? You MUST have a videocard, even if it's integrated, or else where do you connect your monitor.

If this last is your problem, try and search for more up to date drivers of THAT video adapter. If no such a thing as newer driver is available... tough luck.
In the last unfortunate case, try and avoid minimize FS. Try running FS in windowed mode, if you need to access other OS functions often or at all. And for last, try and see if you can upgrade your PC with a real videocard.
Sorry, not much more can be done. :-/
