    Sounds heat-related. How old is the machine?

    Check inside for dust....blow it out from all fans, heat sink etc. Make sure the box is in a fairly well ventilated area. What program are you using to monitor the temp? Seems to be leaning a bit high.

    Also (important) make sure all your fans are spinning up to speed...especially the on over the heat sink.

    Did you build this machine yourself? It's entirely possible the thermal tape or thermal paste has dried out, thereby reducing the contact between the processor and the HSF. If that is the case, it would be wise to (only if you're comfortable with it) remove the HSF from the processor, "carefully" clean the residue from both sides and replace it with a quality thermal paste.
