Stuartli 17:35 25 Aug 2006 Have you switched off the screensaver or other power saving/protection means?Another way to prevent them cutting in is to click the mouse every few minutes (inside the time set for a screensaver to operate). Pineman100 18:05 25 Aug 2006 It's almost certainly some background running application that's causing Defrag to stop.Restart your computer in Safe Mode, and run Scandisk from there. It should be fine. Rhuddlan 19:30 25 Aug 2006 Thanks for the reponses.I am running Windows XP Home SP2.It's the standard defrag windows program.I haven't got a screensaver switched on.Will try in safe mode tomorrow (i'm off out to a party now!)Report back tomorrow.Thanks.Mat.
