I'd be very concerned about that CPU temperature. It's unusually high. I'm also curious about the statement you made regarding the fact that it has done this since purchase. Did it reboot like this IMMEDIATELY after purchase, when it was still in new condition, or did you use it for a while before this behaviour showed up. If it did this from new state it should have been taken back to the supplier to be fixed, as it was not in a usable state. Bit late to be worrying about it after two years :eek:
I'd suspect that the processor heatsink/fan has been carelessly fitted. Sometimes, if the heatsink is moved sideways as it is clipped down, the pad of thermal material between processor and heatsink can 'tear', leaving a poor contact and allowing excess heat buildup. Perhaps that is what has happened on your system?
I'd suggest you replace the current heatsink/fan with an aftermarket one. The best of the still currently available for price/performance, in my view, is the Coolermaster Aero Jet 7+, and the best thermal paste to use is Arctic Silver 5.
You'll find description of the procedures necessary in
my article here, although the recommendations for heatsink/fan and thermal paste in that article are now out of date. Replace them with the recommendations above.
You should also be attentive to internal cleaning, airflow and the tidying up of internal cables. You'll find more information about that
in this article.
