My computer is approx a year old

MSI-z170 Pro
I3 6100 CPU
EVGA 650 GS PSU
GTX 1060
250GB SSD Samsung 850 Evo

So recently, randomly my computer loses power, and reboots itself.
It's not overheating though.

What are the possible causes for this?

-PSU bad? Only a year old
-Software? Virus?
-Loose connection?

How do I find/fix it

if its a short disassemble it and build it while checking all wires for any that have the protective casing worn off.
as for mini dumps just download bluescreen viewer by nirsoft and if you see any entries screens hot them for us.
as for psu well you'd need to swap it out with another.

This is probably best idea, if you have a Psu lying around you could swap that out before tearing everything out, if not check everything 1 by 1 and re assemble before thinking its faulty comps
