PC restart when playing games

[Uden Beater]

Hi, my pc had an issue whenever I play games. from lite to intensive title. I don't know what the cause of it. 

 

What I have try & look in the past:

- Reseat my CPU, RAM & GPU

- CPU pins on mobo didn't bend
- CPU & GPU temps not that high

My specs:
Intel i7-6800K

Asus X99M-WS 

Kingston Savage 16gb 2133mhz (2x8gb)

Zotac GTX 1070 AMP

Micron 1100 512GB m.2 ssd

EVGA 650W GS

 

Everything except for cpu and mobo are from previous build
CPU are brand new
Mobo I bought off ebay which has no problem the first few months of using

 

BIOS ver. SB05H0

Win 10 Build 18632

What kind of restart ? Hard restart ? BSOD ? What's stop code ?

My first guess would be drivers or a lightly borked windows update.

I think it's hard restart. No blue screen. Q-code are AA (reserved for ASL)

Run MemTest86. Try to run only one of DRAM sticks (both of them separately) in different slots. Get some other CPU\motherboard\PSU to test them.
