I think the Sendori virus has been a big part of this problem. If I can't get consistent restarts, I am going to take your advice and perform a clean reinstall.
I'm not familiar with the other choice offered for erasing your hard drive, but I am quite familiar with DBAN. I use it regularly when cleaning up computers for donation to our local schools.

DBAN is a self-contained boot disk that automatically deletes the contents of any hard disk that it can detect. This method can help prevent identity theft before recycling a computer. It is also a solution commonly used to remove viruses and spyware from Microsoft Windows installations. DBAN prevents all known techniques of hard disk forensic analysis.
