This sounds like a problem I had years ago - I think I was running either Win 3.x or 95 at the time - when I tried to de-frag a hard drive and de-frag kept restarting. I even left it running all night once, for the same result. It turned out that I had a screen saver running and every time the image changed, it reset de-frag to zero. Switch off all screen savers, and de-frag ran as it was meant to. Sounds like every time the image changed in your desktop, it woke your computer up !
Sounds like you have a choice - a pretty background or a computer that goes to sleep !
