I have a very unstable AMD K6-3 400 / Asus P5-A system and I suspect the problem is a conflict with the video card. Would anyone care to trade a comparable but sufficiently different video card for a ATI Rage 128 Pro 16MB? Note that the ATI video card came with my Intel based Dell and works just fine in it. It just doesn't work in my AMD system and I don't have another video card to try in it. Mike
