My mother-in-law was given a used Dell Intel Celeron with an upgrade to 386 computer (i'm not sure on the exact specs). When I hooked it up for her it starts to boot up properly, the Windows 98 screen comes up full size, but when it comes up to the box to enter to password the screen shows 4 mirrored images (w/4 mouse pointers). When I get to the desktop again it shows 4 mirrored images. The computer operates completely normal except for the way it comes up on the screen - anything you go into comes up w/4 exact images in miniscule size. Can anyone give me any advice as to why and how to fix this?
