Check display settings by right-clicking the desktop; choose Properties in XP or Personalize in Vista, then Settings. If you can't increase resolution and color quality, click Advanced, Adapter. If Standard VGA Adapter or another generic adapter is listed, download a driver specific to your PC. If your adapter is there, try a prior driver version. In XP, click Properties, Driver, Roll Back Driver; in Vista, open the Personalization Control Panel, choose Display Settings, Advanced Settings, Properties, and click Driver, Roll Back Driver. If you don't know how to do this, set up an appointment with me to do it for you.
