Question PC shuts down while playing certain games

[NachoVarga]

Ryzen 7 1700
2x 8GB DDR4 Ram
MSI 980
MSI A320M PRO-VD PLUS
Corsair CS650M

Shortly after starting any game pc will reboot. Only noticed it happened with Brawlhalla, GTA V, and Golf it.

CPU temp is fine. Tried removing one of the RAM sticks and reduced the chance of happening when playing Brawlhalla but not on GTA V.

Changing RAM speed to 3200 makes pc shutdown more frequently

New RAM stick did not solve it

Did you increase or decrease RAM speeds? Apparently that's influencing your shut downs , so it could be an issue with your ram speeds.
Also, what's your GPU temps?

Can I just throw in here. Is your exact RAM kit on the motherboard QVL list? I seem to remember people saying that first gen Ryzen was very fussy with memory modules. It may also help to update to the latest BIOS.

With your 'normal' RAM configuration, try running memtest overnight.
