I'm having problems with my Mesh computer shutting off randomly (completely powers down and doesn't re-start). Sometimes it'll run for 30 minutes, other times it powers off at the first start up beep. My CPU temperature is 44c and sysytem temp is 26c. CPU fan speed is 2914rpm. I haven't added any new software or hardware recently. Any ideas?

The usual causes for random shutdowns are:
>Overheating triggers auto-shutdown to protect the CPU;
>Memory module going bad;
>Power supply going bad.
