Most peculiar problem - computer spontaneously reboots!

  1. About a week ago my computer started rebooting by itself in an unpredictable manner. Mostly when not attended, but from time to time while I was using it.

    My first suspicion was hardware: either memory, motherboard, CPU or power supply. I verified that all worked fine. The Motherboard temperature was within normal limits as well.

    To exclude any other possible hardware problems, I booted the system with a Linux distribution (Knoppix 3.9), which boots and works straight from the CD. I left it working for over 16 hours with no problem.

    My next project was to check my OS. I am using Windows XP Pro. I downloaded from Symantec a Zotob worm remover. Turned out I had no Zotob. I cleaned the drive from all kinds of malware/spyware etc with Ad-Aware, Spybot - Search & Destroy and with Webroot Spy sweeper. Checked for Viruses with two anti virus applications - Avast and Trend Micro online.

    I also used VCOM’s Fix-It-Utilities 6 pro to clean up the registry.
    The only thing I didn’t try yet is stopping the Google Desktop Tool from indexing, but I do not think it has anything to do with this. (Correct me if I am wrong).

    So now I am at a loss - short than reinstalling Windows, is there anything else I can do? Did I overlook anything? Did anyone else have a similar experience?

    Thanks for any help.

    My system:

    Asus K8V SE Deluxe
    AMD Athelon 64 3200+
    1.5 Gig RAM PC3200 400MHz
    1SATA 160Mb drive
    1 IDE 120 Mb drive
    LG Super Multi DVD RW
    Sony DVD-R drive
    GeForce FX5200 128Mb video controller
    Floppy drive
    Fax Modem
    Windows XP Pro with SP2
    Zone Alarm

    could also be the blaster virus. :knock:

    you'll need the blaster removal tool
    from symantec.

    It was not the Blaster either. But listening to all the advise and comments here and elsewhere, I downloaded every possible adware defense program, antivirus as well as two Root Kit revealers - one from Systernals and the other F-Secure Blacklight.
    Cleaning up my system was lengthy process, but did not completely resolve the problem. What apparently did it was restoring my system 10 days back. (Surprisingly I could not successfully restore it to several earlier points, even though it seemed like an option).
    It’s been now over 48 hours and my machine doesn’t reboot.

    An epilogue:

    Having played with my computer further, I have identified the actual culprit - Google Desktop Search beta 2 and/or one of the plugins for the program I installed. How do I know? After the machine worked fine for almost three full days, I decided to reinstall the Desktop Search program, which immediately started indexing my files. A few hours later the machine rebooted. As soon as I uninstalled it, it now works for over 24 hrs non-stop.

    I have notified Google Tech Support.
