My old Pentium II machine (not my trading computer) runs Win 98 and is getting tons of fatal error messages, blue screens of death, locking up, etc. I want to use it for scanning, etc., but not in its current state. I run 2000 Pro on my trading computer and have the CD. My question is, can I upgrade my Win 98 computer to 2000 Pro with the CD or do I need the UPGRADE Cd? To clarify, I know I could erase my hard drive and then install 2000 Pro using the CD, but I'm wondering if I could upgrade without having to back up tons of stuff first. I'm not sure if that would solve the various problems, though. Expert opinions welcome. P.S. Would an alternative be to buy an XP upgrade?
