New Build, keeps restarting

Okay so I just finished building my new ddr4 build.

I used these:

Gigabyte H110M-S2H Micro ATX motherboard

Intel i5 Skylake 3.2 locked CPU

Corsair 850watt power supply non modular

Pny anarchy 16gig (8gb x2) RAM

No GPU

Seagate 7200rpm 1tb HDD

Windows 10 64-bit

Now some information about the problem.

My computer was shutting down randomly maybe 3-7hrs after use since build. Now it's more like 10-20 minutes. It simply sometimes makes what I refer to as a power down noise and turns black.

Now I have used this PSU without problem in my previous builds and do not feel that my new build would use 850watts without a GPU on a micro ATX board.

That being said, last night my computer had a Bootmngr is missing error and I had to reinstall windows.

All of this has led me to two conclusions. First, since the 1TB HDD is a couple (not many, and really underused) years old, it might have now started failing. I had windows vista on it prior to repartitioning it to Windows 10 with the new build.

Next. Some will say is the heatsink properly connected? Well this is my first time with Intel so I believe it is. What I did was I seen thermal paste was already on the heatsink, so simply placed it in place and pushed each pin down until I heard a click. I did not spread the thermal paste. To m, it feels solid and all of the pins look secure looking at the back.

This leads me to what I fear: Either the motherboard or CPU itself. I have watched the CPU at idle and it seems to run at 39-30 degrees Celsius. Seems normal enough. It has no of been processing anything I throw at it including world of Warcraft and yadifx2 video interlacing. So I think it may be the motherboard.

Any thought or suggestions I would greatly appreciate. Since the motherboard is just a micro ATX and was not expensive, I have no problem replacing it if you experts feel that is the true cause. However, I don't have money to keep buying new processors and such as I still would like to add an ssd and gpu to this build and that adds up quickly.

Thanks.









 
with a new build make sure the mb has the newest bios on it. use hardware info set it to sensor and logging make sure the 12v rail is holding. on old power supply and haswell and newer cpu. if the cpu goes into c6/c7 sleep mode and your power supply not rated for newer cpu they will shut down do to how low the new cpu goes.
 
Possibly motherboard or Ram. I once had a motherboard that went south on me, and was causing the ram to fail. When I would use my computer, the windows install would eventually get corrupted because it was reading info from the ram and I'd have to reinstall after a couple of months. Took me forever to figure that out.

Like I said, my PSU is a corsair 850watt I've used since ddr3 was just new. It has never given me problems in the past. I changed all the cords around and rebuilt the computer to make sure nothing was loose. I also reapplied new thermal paste to CPU to make sure that was not the issue.

So far it seems to be running okay now but like I said, it ran okay for a while before this started. I will report back. If this happens again, my friend is being over a psu to test. If it happens again, I have a 2nd HDD to test. Happens again, I think im getting a new Mobo.

I really don't think it's the RAM as it's brand new, and I have 2 8 gig stciks (overkill) and all clock speeds run normal on the ram.
