Crazy X800

Long story but my Dad and stepmother have a computer that had some sort of error one day, so they took it in to the Geek Squad (I know :-/). Well, when we got the computer back, they said they had to reinstall windows and blah blah blah. Problem is, now, there are strange lines and dots on the screen and other weird things, so I go in the the Catalyst Control center to check the settings, and this is what I see...


These are taken straight from the control center, black dots, lines and all. The Vid Card is a Radeon X800 Pro, with .11 drivers. I really don't know what is wrong. I have a 9800 Pro on my own computer with the .11 drivers and everything works fine. I've tried tweaking settings and rolling back drivers, but I can't seem to fix it. The computer is from Gateway and if anyone needs anymore information, I can try to get it.
Thanks, ;)
