Laptop random shutdowns

Can someone tell me every single possibility of my laptop for randomly shutting down?
Here are the ones I know that ISNT the cause:

Overheating isnt an issue. - GPU/CPU peaks at 65c (during gaming)

RAM/Memory is fine. - 4GB RAM (the game I play isn't that memory demanding)

Motherboard is also in working order. - (did complete system restore and checked if there was any component problems, everything went fine.)

Did a ESET complete scan, no errors.

Yesterday I haven't had any shutdowns for hours, and as I said its random, it shutdown within 20 minutes today.

Battery is also in excellent condition, so is the charging status.

Heres the laptop model: VPCF116FX

You said it's shutting down, or is it restarting? if it's shutting down entirely, it has to be hardware failure induced by overheating, faulty PSU/motherboard, or a short circuit which can be caused by a faulty PSU, power connector, and/or dust. If it is cleanly shutting down (like you see Windows shut down screen n such) spontaneously, then you either have malware or your Windows copy is not legit or not has been activated and you've gone beyond grace period.

Also, I'm not sure how you can ascertain if a motherboard is in working order, especially if all you did is a system restore. There are no diagnostic tests for motherboards outside of a POST card and some other miscellaneous testing items.

If it's restarting as opposed to shutting down entirely, then you can provide us a JCGriff Report, otherwise get your warranty ready, because you're gonna need it.
