Serious, serious question

Alright, this question may sound weird, but here me out:

I've been trying to set up a network in my home for about three months now, but my brother refuses to budge on his spyware-ridden, memory-drained, no-disk-space-having computer.  He's using a Pentium 3 2.0GHz with 256MB of RAM.  The only upgrade of any kind he has is the GeForce 4000 card I accidentially left in there, so he has a dual monitor set-up.  He even has an external hard drive, but refuses to use it/reliquish it to anyone else.

I've watched Windows notify him endlessly about how his system files are corrupting, but he won't run any utility to check the disk for errors.  I feel a need in helping Windows out in dying, so that I can just wipe the machine and put XP Pro on there so he won't complain.  I'd use Linux, but he didn't like how it isn't Windows (I tried a LiveCD).

Does anyone has any crafty methods of getting his computer to just crap out COMPLETELY so I can just format it and have my merry way with it?  Any inconspicuous methods will be greatly appreciated.

If you're in a 240V country, nothing will happen; the computer just won't start. In a 110V country, though, flipping the switch can fry the computer, although newer ones may sense the overload and shut down automatically.
