New system randomly restarts

[Iroul]

Hi all,

 

I have recently built a new system and it has been troubling me since then.

So, here's my system:

 

Case: Coolermaster Elite 130

CPU: Intel i7-4790k

M/B: ASRock Z97E-ITX/ac

RAM: Samsung DDR3 PC3-12800 16GB (8x2)

SSD: Plextor M6G 256GB M2.2280 (I know...Z97E-ITX/ac does not support 2280 but I was able to fit it in)

         Samsung 840 EVO 256GB

Cooler: Coolermaster Nepton 120XL

PSU: Seasonic M12II-620 EVO

VGA: "Empty"

 

My VGA is empty for now for future GTX980 or GTX980 Ti (I was going for 980 but 980Ti is now very tempting).

Anyways, my new system restarts randomly on its own without any prior warning.

I have checked CPU and M/B temperature using ASRock's A-Tuning software and also in the BIOS,

and they both are staying around 30~35 Celsius (86~95 Fahrenheit) normally.

I am not running anything that might cause the system to run over the limit when my system restarts.

And it seems like it usually happens when I first start my system when I get home after work.

Then it kind of settles itself and doesn't seem to restart anymore.

So I am safely assuming that it is NOT caused by overheating.

 

There is a component that does bug me though.

As I have mentioned above ASRock Z97E-ITX/ac does not support M.2 2280, only supports 2230 and 2242.

But I was able to fit it in without forcing it "too much".

 

 

As you can see in the above picture, my M6G is currently stuck inbetween the M/B and the cooler's bottom plate.

Again, I did not force the SSD in; it just magically fits.

So I am wondering if this is causing some kind of ESD once a while.

 

Other than my M.2 SSd, please let me know if you notice anything that might cause my system to restart randomly.

Well take the SSD out and run the system to see if it restarts.

Sadly, my M.2 is the main drive with Windows installed on it.

maybe try it with a linux boot cd without the m2 in

I have unplugged all the cables and took the motherboard out and realized that I threw away the leftover thermal paste for the cooler.

So I decided to take the cooler out later, after I get a new thermal paste, since I can only take the m2 out after I un-screw the cooler.

But after I wired everything back in together, my system has been awfully stable for a few days straight.

I am thinking maybe I had some cables not plugged in all the way and that was causing my system to reboot?

 

I still am going to order a new thermal paste so that I can try techguru's option though.
