I recently reinstalled windows XP my computer and when it was fully restored i turned it on to find my Screen resolution is stuck on 640x480 and 16bit color. i have a dimension 3000. I can't fix it, so help would be greatly apreciated.
Probably you didn't reinstall the video driver.
EDIT: If you have a Dimension, you'll get them at Intel's website, and as a bonus install the Intel Application Accelerator, but first the video...
