PC Hard-Crashing When Playing Games

So, I'm rather perplexed to what's going on with my PC.

This is gonna be a long read, so please bear with me in this riddle.

It's crashing at (seemingly) random intervals. No blue-screen, no nothing, just as if I flipped the switch on my power supply. It won't turn back on until I unplug the PSU and then plug it back in. My initial thought was "Okay, guess it's time to clean her out." I went into the case and cleaned out all the dust in the parts, but it still happens.

So I was like "Okay, it's overheating" and moved my PC into a more open area, and faced the back outwards to see if the open air will help it cool more than it was when it was kinda close to a wall, and so I could feel the fan to see how hot the air coming out was. It was still happening, and the fans weren't running wicked hot, nor were the parts according to HWMonitor. At this point, I tried updating my drivers and seeing if I could find points where it was recreate-able.

When I'm playing games, such as World of Warcraft, DotA 2, Dragon's Dogma, and PUBG, My computer will instantly crash at random points, or specific points. For example, World of Warcraft crashes my PC after I finish loading into the world after logging in, but only if I was playing DotA 2 before playing it. In DotA 2, it only crashes at the end of a game, when the ancient blows up and I press the button under the victory (or defeat) screen. In Dragon's Dogma, it only crashes my PC if I alt-tab and tab back in. PUBG crashes it randomly.

Okay, cool, I've found some spots where I can reliably recreate this. So I pop over to WhoCrashed, and see what I can learn. WhoCrashed is not finding any logs to analyze, or anything at all, actually. Well, drat. I'm not sure what to do after that, so I've tried a bunch of random stuff, like clearing up lots of disk space, uninstalling programs, doing multiple virus scans, and trying to research the issue online. So far, I've got no dice.


I figure Toms Hardware forums have always been of great insight, so it's the next logical place to turn. I'd appreciate some help in figuring this out.

Solution
Check the oem of a psu before buying it.
Seasonic, Super Flower and Delta are some of the best oems out there, though Delta sells most of their models to pc manufactures such as hp to be used in prebuilds. FSP and CWT are okay if you're on a tighter budget.
Other brands you should avoid.

Seems pretty much a PSU failure. The TR2 isn't the most reliable unit out there...

How old is it? Can you test your PC with another PSU, a friend's perhaps?

You could try pin point the power peak failure with stress tests like furmark or prime95, if you PC shut down while running those it is very likely the PSU isn't able to sustain the demand and shutdown...
 
I would assume your psu has lost it's peak power output over the years and has now gone over the point where it can't deliver enough power anymore.
Do you have a psu you could borrow to test with?
Running memtest86 would also rule out any ram issues.

Another way to test the psu is to run a gpu stress test like furmark alone and a cpu stress test like prime95 alone, if it doesn't crash on either one then run them both together and see if it crashes. If it does, then it's very likely your psu that's failing.

I do not have the option to test my PSU in another PC, nor another PSU to test with mine.

As for those stress tests, I did them all, even at the same time like you suggested, and I did not crash. I appreciate the attempt to help narrow it down, guys!

I'm starting to think it could be related to my GPU drivers. It first happened when I was playing PUBG, and it only happened after I updated my GPU drivers, because I was hoping to get some better performance in the game. If It keeps happening after the next driver update, I'll try to revert back to my old drivers and document what happens.

Update. PSU just died out. I was playing Dragon's Dogma, and out of the corner of my eye, I saw a blue light (which I now know was a spark) fly out from my PC. After which, it would not turn on, and opening the case smelled like burning. I've ordered a new PSU, and please cross your fingers for me, and hope that my other parts are fine.

Sorry to hear...

Which PSU did you order? Hope you bough a proper one.
 


Did you read any of the earlier responses here?
