Make sure you have the OS disc that came with your computer. If it has a recovery partition then make sure you make the discs. Then nuke the HD with DBan and your finished.

Specs:
Acer Aspire 5100
Windows XP Media Center Ed
I do not have the OS disc....(I think because this is a demo computer?....got it for a really good price)
I have a "Express Upgrade to Windows Vista DVD", and a "Acer Upgrade DVD".....which I never used.
I also have a back-up disc from a LONG time ago.....made it closer to the time I purchased the computer, but I dont think I made it upon first use.
