Here's another strange one. My friend's PC was having all kinds of probs while running Win2K. I upgraded it to XP Corp and it ran OK but for the initial boot only. When we try to reboot we only get as far as the white progress bar at the bottom of the screen. It reaches it's limit and then...nothing - it just stops there. Re-installed XP and exactly the same again. Is it likely to be a duff HD? The Win 2K had been OK for some time and then started 'acting up'. Would be grateful for any ideas. Many Thanx.
