My computer keeps turning off?

[ThatSweetGamer]

Everytime I leave my computer alone overnight it will teurn off. I have the settings in windows to never slepp when left alone or turn off. Now the problem can be one or two things, Voltage or a loose plug. The other day I was on my beast of a machine and a thing came up saying "Warning Voltage is 3, Cap is 3.8~~" (I put ~ becasue I forget what the exact number was) and I really don't know how to deal with that. So halp pls! Thanks

Is it overclocked?

Is it overclocked? 

Only the GPU using an MSI program, not afterburner but the one where there is a choice between Silent, Gaming, and Over Clocking modes. I usually will press Over Clock when I game and Silent when just on the internet.

When you finish all ^ with no result, check cpu temps with Real Temp on Prime95 test(0,5h).

The 8150 will not go over 66C and it is also water cooled.
