I recently had to re-install Windows XP on my girlfriend's PC due to a nasty virus. After completing the re-install and doing all the necessary Windows Updates (to XP SP3 and everything else), I still cannot change the screen resolution to anything besides 800x600. I go to Control Panel--Display--Settings and for anything above that resolution, the monitor says "Out of Range." I can click "Advanced" then the "Monitor" tab, then under "Monitor type" it says "Default Monitor" and the Properties tab is grayed out. I'm not sure what to do next. Before the virus and the re-install, the monitor would support higher resolutions.
