crash and automatic reboot on Win 8

#1
I usually leave the machine running. It is set to produce a memory dump and to "automatically restart" upon system failure.

When I came to the computer this afternoon, it said it had crashed and restared.

Here's a summary of the machine by Speccy:

I don't really know what conclusions to draw from that or what to do.

I would appreciate any advice.
