From time to time my hard disc light will come on for no reason (no programs running ) and computer locks. Can also happen if am using Firefox or Word or similar, even when I have good free memory (say 200mb out of 500mb) (sony Laptop running XP) When this happens the desktop icons will not respond and cannot open any program. Cannot use the start button to restart . Can be like this for ten minutes or more.
Use ccleaner on a daily basis to remove unwanted files and also its registry cleaner. Update and run Norton daily and never find any problems. The only other word that I can add is HELP !
Whilst this problem may not be new to the group I am and so would not have seen the origonal answers
Thanks for the help that I feel sure I will get
