Hi guys, I'm going to "donate" my desktop PC to my cousin and to make sure the CPU is
clean before I hand the PC to him, I had deleted all files and sw which I've saved and
installed over the years.
But I've heard that files will still be hanging around somewhere in the harddisk even though
I've deleted them. Is that true ? If yes, how to do a thorough clean-up or I have to send in
to service centre to do it for me ?
