It's going to take some time, but I recommend deleting any programs, personal files (photos!), etc.
Then do a hard wipe in the BIOS, and reformat the hard drive. Throw in a partition or two to mix things up.
And then do it again.
And then do it again, but don't add any extra partitions, and reinstall Windows (or whatever OS, but I'm assuming Windows).
The best way you can erase a hard drive is to repeatedly reformat it and rewrite over it. The more you do it, the harder it is for someone to go back and pull up anything.
