Retrieving information from CPU and how do I erase information from a cpu?

How do I permanently erase information from my cpu, and if I give my cpu to someone, can they retrieve erased information?

There's nothing stored in the cpu, only the hardrive.

As o1die said, the CPU does not store data. Are you using the term CPU to refer to the whole computer?

It's more likely you're worried about your hard disk drive having personal information that could be retrieved.

Darik's Boot and Nuke should do for you what it is I think you want.
