Memtest error: Unexpected Interrupt -Halting CPU0 and computer shutting down randomly

I have recently had problems with my computer shutting off randomly and then restarting as if I had just turned it on. After reading around I found that it might be a good idea to do a memory test. The memtest result is shown in the image below.


Does anyone have any idea what the problem could be. I have tried testing both the RAM modules separately but I still get the error in memtest.

The unexpected interrupt is usually the thermal emergency shutdown, caused by an overheating CPU. Make sure the CPU heatsink is properly seated, its fan is clean and running, and there is proper airflow in the case.

My cpu is at a steady 30 degrees roughly. I can't see this as being the problem but I will certainly have a look and try to remove some of the dust.

Any other ideas?

I'll throw you one from inside hardware, given that it's not thermal.

cat /proc/interrupts point top a timer on interrupt 0. What looks odd is that the PC (program counter is unusually low. You are not going to easily guess what has happened, so I'd recommend a 'Divide & Conquer' approach
