For what it's worth, I had a similar problem on my Mac and it turned out to be my add-on Zip drive... bought a new one (never unwrapped!) at a garage sale for $5 and it works perfectly.

Disconnect any unnecessary hardware (PCI cards, modem etc) and then see if it works better. If so, add components one at a time. You may be able to pin it down on a malfunctioning part. If this doesn't work, then I'd try getting a new hard drive and rebuilding the system on that. If you can rebuild with no problems, then you may be able to add your old hard drive as a slave drive and back up all info before reformatting. This way you'll get more storage as well, or even be able to start up form either drive in case of a future problem. There is probably and easier way then the above two options, but that's what I'd do. Maybe someone else has input. Good luck, Jeremy Swan --------------------------------- Do you Yahoo!?
