With help from peeps here I recently upgraded my sons pc from Windows ME to as he kept getting problems with it. After xp was installed, all went well untill I tried to install microsoft office and I got a blue screen with a fatal error. It said press ctl/alt delete to reboot but would not reboot, it just said "disk error. Reinstalled xp again and all seemed well so took pc to him today. When I got home he phoned to say that the pc had been left on standby and then frozen, reboot showed the disk error again. I am talking him through reistalling xp but it seems to stop at "formatting disk 0 %". Its a 40gb hd, how long will that take to format? As the install worked for me does it mean the hard drive is duff and thats why it keeps giving "disk error" He had loads of problems when Millenium was the OS, so I thought xp would cure things. Any advice would be gratefully received?
