Help! PC randomly restarts itself

[john917]

Hi, 

My PC randomly/suddenly restarts itself. There is no specify timing it is just random. 
This is a fairly new computer I build last year December. This is my first build but it was working fine for the past couple of months. 
I check all the temperature, but when it restarts it self, I was not doing any heavy load just (video and surfing the web).

 

CPU: Intel - Core i7-6700K 
CPU Cooler: Cooler Master - MasterAir Maker 8
Motherboard: Asus - Z170-DELUXE 
Memory: Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000 Memory  
Storage: Samsung - 850 EVO-Series 500GB 
Storage: Western Digital - BLACK SERIES 4TB & 2TB
Video Card: Asus - GeForce GTX 1060 6GB 6GB Strix Video Card  
Case: Cooler Master - MasterCase Maker 5t ATX Mid Tower Case  
Power Supply: EVGA - SuperNOVA P2 650W  
Operating System: Microsoft - Windows 10 Pro 

Anyone encounted such a problem before?

What are your temps like?  All the fans running and clean?  Make sure the system is clean of dust, etc., along with the cpu heatsink.  I clean my system once a month with an air compressor making sure to block the fans so that I don't burn out the bearings in them with the air from the compressor.

 

Maybe it's time to "refresh" the thermal paste on the cpu?  Don't forget to clean out the PSU too.  Good Luck.

CPU temp avg around 40, 
GPU around 40 too.
All fan are runing fine and there are 6 fans in total actually.
It is system is actually quite clean, I rarely use it due to school, but currently this past 2 month is the holiday so I use more (~16hrs a day)

Try removing the rest switch from your motherboard. They look like this

Your temps are fine.  Are you overclocking?  If so, try backing down on the overclock say 200-300 Hertz give or take. Anything running in the background?  650 watts should be okay too.  I have the same exact case (just got it about two months ago), and to help with heat dissipation I removed the red vent thing from the top.  I also have an AIO on order from Newegg that should be here at the house in a couple of days, so anyway, looks like you have the heat and temp things under control.

 

How about power cords?  Everything plugged in like it should be I assume.  Make sure the 24 pin power cord is seated all the way.  And the ram is all seated tightly.  Good Luck.

Only the reset switch. Sorry if I confused you.
