Hard Drive Cleaning

Sup /tech/

So, what do you guys use to remove history from your computer. I am getting a new computer, and I have files on this I want to completely get rid of. I deleted them with recycle bin, but I know that still leaves traces. What kind of software should I use to get rid of deleted stuff for good?

Paranoid much? Two wipes is enough for most purposes, five if you want to be dead certain. Even after the most basic secure wipe someone is going to need several months with an electron microscope to get back your Captain Picards.
