Not sure where i can find it in bios but i'll check later after i grab some grub.
If it's doing it randomly, then it's not load line calibration.
LLC is a bios setting that helps to boost Vcore when under heavy load to counter the effect of voltage drop during high current use, (gaming).
Some mobos implimented it less than ideally, such that when you stopped a game, it lowered the Vcore too much and you'd experience crashes.
Assuming for the moment that your hardware is good, your issue sounds more like one of two possibilities; either an intermittant "Turn on signal" connection issue which could have several causes, or a momentary short that causes the PSU to shut down for self protection.
You might try manually wiggling the green wire in the 24 pin connector and the 24 pin connector in general.
Could be the wire itself, or the connector on the mobo.
If that green wire looses its connection to ground, the psu turns off.
Shorts are harder to find, and take more patience;
The best way, and really the only way, is to take the mobo out of the case and put it on a table, putting the box it came in under it is pretty standard "test" proceedure.
Then hook up the PSU and gpu if you don't have onboard, and 1 stick of ram to start..
It's not uncommon to find that you've dropped a screw or something behind the mobo, or a standoff in the wrong hole, or pinched a wire.
You just have to keep eliminating possibilities.
