Solved

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.

  1. I hear people constantly saying negative things about the VS power supply. Don't be surprised if that is the issue. The problem occurred after cleaning. Is the fan in the power supply turning?
  2. You need a better PSU, the VS 550W is a piece of junk.

    Anyone of these 3 would be better.

  3. I would double check all your connections, make sure everything is properly plugged in snug.

    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.

    You can go purchase a power supply, use it for testing, hold on to the receipt and make use of the return policy if the VS isn't the issue.
    But that's the only way to find out.
