PC shuts down while playing high end games like Doom, Dark Souls 3, but works perfectly fine while surfing, or playing DotA 2.

I cleaned my PC a few days ago, and after re-assembling and setting everything up, I booted the pc. Everything was working quite normally. I play a lot of DotA 2, and the game was working without a single issue. There is a demo mode in DotA 2, in which you can spawn bots, items etc. to experiment with or to preview cosmetics. I spawned like 20 bots, and started casting different spells on them. 10 seconds after, my PC froze, and shut down.

I posted this in r/DotA2, just to see if it was a common bug or some issue on my end. It was only on my end. No other player experianced this.

1 Day later, I got bored of DotA 2 and started playing Doom. I was able to play for about 2 minutes, and then the game crashed the same way as it was crashed earlier. I got suspicious, and tried playing Dark Souls 3, and again, crashed the same way, after 1 minute. I also tried running 3DMARK benchmark to see what happens, the PC crashed the moment benchmark started running.

There is also a game called Spellbreak, which is in beta testing, which also causes the PC to crash, despite being low end in terms of graphics.

I tried these things to fix this issue.

I first reapplied the thermal paste to CPU carefully with dot method, and tried playing the games to see if it was CPU tempreture issue, it was not. I then checked all the cables, and also checked if the PSU fan was spinning or not, it was running perfectly. I also tried changing the PCIE power cable of the GPU to the extra one. I monitored the tempretures again. And here's when I saw something strange.

Idle temps - CPU : 35 to 40, GPU, 40 to 45 DotA 2 temps - CPU : 40 to 45, GPU : 60 to 70

Doom, DS3, Spellbreak temps - CPU : 45 to 55, GPU : Jumps from idle 40 to straight upto 82, 87, 90, 93.

Even when I started the game right after the windows was loaded, the GPU temps would shoot rapidly to 85 and 90. I checked the GPU fans, they are running properly (sucks the air towards the processor). I was reading these temps on HWMoniter, I also checked on GPU-Z, and the same thing was happening.

I then re-installed the AMD graphics drivers and tried again, no difference in results. So I turned on the AMD chill mode, that resulted in about 7 to 8 degrees less tempreture, but the crash still occured.

What should I do?

P.S. : The DotA 2 game sessions are 1 hour long each game, and I have played around 8 matches since I cleaned my PC, with no issues, and yet these other games are crashing, that's what confusing me. CSGO is also working without any issues.

When I play Doom, The game stutters when looking at multiple demons, particle effects, and runs smoothly when looking at walls. This might sound like a low end PC issue, but the game used to give me solid 80-90 fps at ultra settings before I cleaned my PC.

Here is my build -

I have a question, If my power supply is failing, should that only affect to games with high performance usage, or should it affect overall everything? The Dota 2 and CSGO games run without any issues for hours, My PC still stays on overnight.

Can I test the PSU myself?

I checked everything I can. PC otherwise runs excellently, only when I try to play high end game like Doom, It shuts down.
 


Yeah, throw it in the garbage, that's the only test you need to do.

Then buy a good PSU.
