This sounds like one of the FEE (Frequently Encountered Errors) for Windows.
You've hit this FEE if your SVGA card has an autosync mode and it isn't
disabled.  Windows detests talking to a video card which suddenly changes
modes without having been told to do so by Windows; if this happens Windows
throws up and does strange things.
