Help diagnosing X58 UD5 shutting down,LEDs all lit up.

Computer has been shutting down on it's own while I am out. I'll come home and find all the LEDs all lit up. I searched the internet and checked the manual. I can't find anything on what all LEDs lit means. Its is the rig in sig. X58 UD5 rev 1

I have this mobo as well and mine did the same thing. Try clearing cmos and take out the cpu if that does not work try a different power supply.

Also ensure the ATX power for the motherboard is secure, had weird issues with a similar board, turned out the clip broke and the power cable was barely plugged in.

Cleared cmos and it has been ok so far thanks.
