Look where your screen connects................if it is at the very edge or bottom rather than amongst those little blanked off expansion slots, you have on board video. Or look inside and see if you have a card in either a white or (shorter) brown expansion slot............that would mean that you have a video card.
The problem with onboard video is that it shares your RAM...............like it steals a part of it. Old machines had memory chips to support the onboard video, the newer boards rely on you having enough RAM..........I have a Win2000 test machine across the room.............it has onboard video and that takes 64Mb of my RAM.............OK...........out of 1024Mb of PC2700 that does not matter, but once you get down to 256Mb, it starts to hurt.
I stand by Morgana~ and my original advice...............increase the RAM
