Smart BuG shuts down computer

Any advice most welcome:

Sony Vaio laptop 933Mghz, 256MB RAM 30GB HDD WinXP Pro 1st edition, no SP2. IE6

BuG shuts down computer when threatened, such as:

Windows update
Pest Patrol install
SpyBot scan
Safe Mode startup
WindowsXP reinstall to same drive
WindowsXP clean install on NEW DRIVE!
Drive with Win2000 preinstalled fails -- BSOD
Sony BIOS flash utility (windows application)
Knoppix search for rootkit from CD

Successes -->>
IEspyAd installed to restricted sites list in browser
I interrupted a SpyBot scan before it crashed to delete about 10 problems. NOD32 deleted over 200 trojans. Just deleting directories helped as well. HiJAckThis scan and Fix improved some issues. Still the BuG persists and shuts down the computer when threatened.

The real question is where is this BuG? in the BIOS? Battery removed, BIOS settings restored to default but no effect on the BuG, of course. This BuG has staked its claim and it doesn't want to give ground.

Many the BuG's sidekicks have been tromped on, but still he vexes me.

SpyBotSD crashes while scanning CoolWWWSearchFeat2.dll

What would you do?

my 50 hr assessment

stealth BuG in the MBR. Once he takes up space in memory, he won't give it up >> power off rather than lose ground, reload again. Once Windows loads, he can call on the disk files that are also stealth and they have a list of .exe files, URLs, msi files, for triggers and probably some random number / timers tied to windows events to just keep things messy. Another stealth .dll keeps a few bad guy addresses and he phones them when there is a little available internet connection time. System is slowed by their 'business' and the longer it is left to its own, it will take over. Stealth DoS BuhGH. More fun than a barrel of bad memory chips.
