I have some knowledge on PC but im stumped aswell
When I turn the PC on i get the xp loading screen with the blue bar going across it,
the problems are
1. This stops and stays frozen, so i have to restart computer 3 or 4 times to get past this screen
2. when I finally get past this screen I get to my desktop, This then Freezes and have to restart the computers again,
3. In the unlikly event i actually get a program running it freezes up after about 5 minutes
I have reset the bios setting to fail safe (F6) but the problem remains, I dont have the windows XP install disc as someone else installed XP on this computer for my mate, and has dissapeared.
So any help given will be great
