Hi - I have Windows Home XP and suffer from seemingly random PC freezes. When the happens, the screen hangs and CTRL/ALT/Delete will no respond so I have to use to reset button to reboot. There are no events logged so I cannot tell what it causing it and no common programs that are running. I have updated my graphics driver and all other drivers are up to date (there are no conflicting ones as far as I can tell). Tonight, I was carrying out a virus scan only, left the PC and came back to see that there was another hung screen. My pc is 3 years old and has always been ok, I have just switched over to Broadband but have the latest driver for that... Any ideas what I can try next?
