strange problem when burning to cd

[castew]

Hi I've got one heck of a strange pc probelm going on here and im running out of people to ask about it.

Basically whenever i try write to a cd it gets part way through and my entire pc powers down. I even have to unplug it from the mains for about 5 seconds before it'll turn on again. so far i've tried these things....

ive changed the hard drives that are plugged in
used another instalation of windows on another drive
changed the ide cable
changed the master and slave settings on the ide channel
changed the power supply
changed the cd drive
tried slowing the write speed down
turned off buffer underun protection
tried burning to cd with 5 different applications

None of thats changed anything, I cant find anything on google about it and to add to it all event viewer aint logging a thing when it happens.

Any ideas would be very very welcome indeed and bonus points awarded for the inclusion of a monkey in the fix! A basic summary of my computers spec follows...
