graphics card PC shuts down during certain games in complex situations

[BlueMrLahey]

I've been having this very specific crashing issue with my PC and I've tried but haven't found many existing solutions online.

Basically what happens is that in a few specific games, my PC switches off completely when some big event happens and sometimes just for fun.

 

My PC shuts down when;

- I play PUBG on anything other than all low settings and take a shot

- I was playing HL2 Ep2 and the

final rocket launches (literally at the end of the countdown)

- Most recently, Half Life Alyx when any big transition happens like an explosion or environmental event like

a train crash

 

In other games like DOOM Eternal I'm playing on max settings for hours without any issues, It's just these specific games.

 

I've monitored my temps while trying to get it to crash

GPU - 67c

CPU - 45c

 

Seems normal to me.

 

I've changed motherboards, and RAM.

Only CPU, GPU, and PSU are unchanged because I can't really access alternatives right now.

No OC on anything.

 

Operating System - Windows 10 Edu 64bit

 

Specs - 

GPU - EVGA 1080ti SC2 Hybrid

CPU - i7 8700K @ 3.7Ghz

Mobo - ASRock Z370M ITX/ AC

RAM - Corsair Vengeance RGB PRO 8x2 3000Mhz

PSU - SeaSonic FOCUS Plus Gold 650 W 80+ Gold

 

Half Life Alyx gives me an error where it says I'm low on GPU Vram, but I have 11GB? So maybe there's something wrong with my GPU VRAM?

 

Any help would be appreciated, and please let me know if there's any additional info that would help.

Thanks.

Either the motherboard or the PSU cannot handle the load, just a wild guess. 

 

The HLA error probably has nothing to do with the board shutting off.
