Have you tried reseating the cpu heatsink? It may be overheating, I've seen that a lot. You may also want to check the TIM and reapply if what you have now is old or starting to dry out.

Have you check your RAM compatibility with your motherboard. I got a similar issue with mine 6 months ago.

Thermal Interface Material.
Make sure your heatsink is properly seated also, as those stock Intel ones can be a real bit** to get on right.
To reapply TIM , wipe if off with some alcohol, and get some Arctic Silver 5 to replace it.
It is definitely overheating.
