This old box has been parted out and pieced together more times than I can count. I'm not even sure how much of the original HP is left other than the MoBo. It's been running 98SE but I can't even remember if that's the original or if it was upgraded from something else. It's tried to die a couple of times before, but I was able to resuscitate it one way or another. Well, a couple of days ago, 98SE decided it had had enough. I was having problems with any browser accessing any web page. I wasn't sure if it got some kind of bug or something got corrupted. I went to Windows and checked around (was able to get there OK), and that told me IE8 should work. It downloaded OK, but wouldn't install. Things just kind of went downhill from there until it would only boot into Safe Mode. So, instead of trying to fuss with it, I remembered I had a spare copy of XP Pro laying around. Hit a couple of sites and found a WD 80GB HDD for $15 shipped. Got that today, but I haven't started the process yet. I just hope the CD drive works OK. I'm not at all sure this MoBo and CPU will even support XP, and I don't know what it is to be able to check. I may end up getting another MoBo/CPU bundle. I found a few for under $100 shipped. Reading a few sites, I found some mention of XP going to the BSOD if you don't have certain drivers available on Floppy, so who knows what might happen. Yeah, I know I could get a refurb box for $200 or so, but if this works, I'll still be ahead; sort of. This is like a fourth machine in the house, so if it dies, it's really not that big of a deal. Sooooo, any suggestions on what to watch out for?
