Question: Well my sister right clicked the mouse and then she went to properties. Display properties showed up and then she went to setting at the end. She went to advanced at the end. After that she went to adapter, she click on properties. Then she went to resources and she change settings based on system to settings based on automatic. Now after the screen says Windows XP loading the screen blanks out and I can’t change it because I can’t see anything. Please help me.
Answer: I would boot the computer into Safe Mode which will use a generic driver and may let you see what you are doing again to be able to go into the adapters properties and change the settings back to the way they were. Or you can try choosing Last known good configuration from the Safe Mode menu or even a System Restore from Safe Mode if you can get into Windows.
If that doesn't work then you will need to find a way to have the computer recognize the video card again and reassign the correct settings. If its a PCI card then you can take it out and try another PCI slot. If its built in or an AGP card you can try to borrow a video card and install it and use that one to get into the system and see if it lists your other video card still and change the settings. If you cannot find a way to get it back then you may want to try a Windows repair installation and see if it detects and reassigns resources to your video card. A repair installation will reinstall Windows over your existing copy and leave your programs and files intact. Just be warned that there is a chance it may not go smoothly so you may want to find a way to backup your data.
