Temperature is one of the most difficult variables to measure accurately and readings are more likely to be below true temperature. Your PC seems to halt at about the same CPU temperature but that would probably mean about the same time since startup, too. You almost certainly have an overheating component - could be the CPU, a video processor, an onboard chip or the power supply or ...

You should be able to confirm that something is overheating by opening the case and blowing into it with a real good fan. While you have the case open make sure the power supply fan, case fan(s) and CPU fan(s) are all working. If you get longer run time while blowing lots of cool air into the case - or no crash at all - you have a heat problem and you need to figure out what the culprit is.

Heatsinks need to be mounted flat against the chip surface. It is ultra easy to mount the heat sink on flip chip style CPUs with the heat sink contacting only one edge of the CPU - that will overheat the CPU very quickly. If not the CPU, feel around for warm components after the PC halts(with the power off}.
