Hi all, as part of my transition to broadband, I have bought a new PC to replace my ageing 650Mhz Pentium 3. I will probably end up giving the old PC to my brother, or flogging it on ebay for tuppence if he doesnt want it.
So, whats the best way to go about removing all traces of me from the hard drive so I can sell it without worrying about the new owner finding my passwords/internet accounts/porn

etc? Do I need to reinstall windows, or if not what should I delete? Are there any programs which will do it all for you?
Thanks.
