If you REALLY want to erase everything then read here http://www.zdnet.com/blog/storage/how-to-really-erase-a-hard-drive/129

Secure erase is as good as it gets for free. And THEN afterwards reinstall windows.

If you have recovery media for the OS, boot it using the UBCD and the tool DBAN on that CD to secure erase the HD. If you don't have recovery media, but if there is a recovery partition, look for a utility of lenovo that allows you to create such media. Once you have created the media use the tool I mentioned above to securely erase the HD:

Once the HD is securely erased use the recovery media you created to reinstall the OS.

Neither will deleting partitions nor formatting them erase all traces of data. You must use tools similar to what I mentioned to achieve this.

About DBAN
Darik's Boot and Nuke ("DBAN") is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.

The link I sent you to download Secure Erase from ZDNet is all you need then. Will do a secure wipe of the hard disk and make it non recoverable.

Most Clients will want the PC with the OS it was originally delivered with, as most PC's come with a pre-installed OS and an OEM License for that OS. Also most modern PC's, when you buy them, don't come with either, installation or recovery media anymore, but rather have a recovery partition which allows you to return the PC back to the factory delivered state, with just the original OS. If you use DBAN to wipe your HD you'll end up with no OS and no recovery partition. So if you didn't use the utilities that came with the PC to create recovery media your customer would then have to buy a new OS and install that. I don't think he'd be happy with that. So I mentioned that above as a precaution you should take before wiping everything from the HD.

Apart from that I mentioned DBAN before cwstad2 (it is included on the UBCD I asked you download and boot from). Good practice on this site is to accept the first correct answers, and not those that came a lot later and mention the same answer....
