The Hall of Heroes

Hi,

My desktop computer running Windows 8.1, with all patches installed shuts down without warning a couple of times a week - seems to be random as I can see no pattern to when it happens, let alone why. Very annoying as there is no time to save my work - the computer just shuts down suddenly - shuts down - does not restart.
Can anyone help me find a solution?

Please help.

I didn't find the right solution from the Internet.
