Do you mean that you uninstalled your ATI graphics drivers? (The generic
Windows graphics drivers would run at 800X600, which would make everything
look large.)
You may have an installer for them on a CD that came with your system. (Is
it a notebook? Desktop? Onboard graphics? Separate graphics card?) You may
be able to get some information as to what display adapter is in your system
in the Display control panel (Settings tab, Advanced button, then Adapter
tab).
If it's a desktop PC, you can also get graphics drivers here:

If it's a notebook, it may be best to get the drivers from the notebook's
manufacturer.
I'm sorry to hear that Best Buy did nothing for you. It shouldn't have been
a big deal.
