Evening all. 
Got a bit of a stumper here. Here's a bit of background first.
Got a desktop tower, Epox 8K5A2+ motherboard, Athlon XP 2400+ processor and 512mb DDR mem. It's circa 2002 and has been the workhorse of my machines, having previously ran Windows 98, then XP, then latterly an XP/Ubuntu dual-boot combo. No problems at all.
Anyway, I decide it's time to upgrade and sell this machine to the brother-in-law, he asks me if I can wipe it and just have XP on it. No problem I say. Wish I hadn't said it now.
Every time I go to install XP, at some point during the install I get the dreaded blue screen of death with the "Hardware Failure. Contact your vendor for support" message. Now, I've hit the M$ website and looked up the problem, it could be faulty ram (nope, as I've changed all six known working sticks I have, plus the slots they go in, same problem) or the graphics card (swapped out with another, same problem) and so on. Oddly it did manage to complete installation when I disconnected the floppy disk and was working fine for about two hours. I was starting to believe I'd cracked it until it happened again
Oddly enough, out of frustration I installed Ubuntu 10.04 on two occasions and that installed and ran just fine, no problems at all.
So I've reached the point where XP says there's a problem, Ubuntu not.
Anyone had this before? I've been building my own machines since 2000 and not come across this problem before now.
