So I was installing a barton 3200 in my sisters computer and I applied the thermal paste to the processor and to the heatsink (where i wiped the original paste off). What I accidently did was clip the heatsink on 'backwards' so the paste on the heatsink wasn't touching the paste on the processor. So I booted it up, checked the speed and then went to download MBM. At which point it rebooted. 'Oh shi-,' I thought as I checked the temperature in the BIOS. 118°C I win. Until someone else posts a higher one. In my defence the heatsink is so much easier to clip on the way I clipped it on originally, the 'correct' way means forcing a screwdriver between the small gap between the heatsink and the PSU.
