Can anyone help please ? I seem to be experiencing random crashing, that is, sometimes my machine runs perfectly fine for hours, and then totally unexpectedley crashes on me. I have tried various disk clean up utilities (from microsoft to CCleaner), but nothing seems to work. I seem to be trying in vain.:blush: Some time ago I had to reinstall windows xp pro, I'm not sure if I reinstalled it correctly !! I am on a basic setup Pentium 4 processor 1.60GHZ 512MB How can I tell if my memory is full ? Should I wipe the Disk totally ? If so how ? Thanks for your help !!
