Windows 10: What could keep crashing my PC?

So this is a fairly rare occurrence, but it happens often enough at very bad times. It only happens when I play a game called League of Legends, now this is about the only game I play so I don't think the problem lies within the game client itself but rather just the fact that I during this time put more stress on my computer, but I'm not sure.

So what happens is; I'll be playing the game and all of a sudden my PC freezes and whatever sound last played is now stuck on a single everlasting note. I can't access anything during this period and the only way to fix it is through powering down my PC. And here's the frustrating part; the literal instant I press down the power button, everything starts running just fine again but at that point it's too late because I already pressed the power button so everything proceeds to shut down and I can't stop it. What could be causing this?

I checked the event viewer but there aren't really any errors happening during the time of the crash. There is one error that pops up every now and then which is Kernel-power 137: "The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance." Could this be causing crashes?

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Windows 10 keeps crashing

Hi,

There are many possible reasons why the computer will keeps on crashing. One of which is missing or corrupted system files. For us to further isolate the issue, we suggest answering the following questions:

• What exactly are you accessing/doing when the computer crashes?
• Were you still able to login to the computer after it happens?
• Can you send us a screenshot of the error messages or mini dump that you've received?

In the meantime, if you're seeing a blue screen when the computer crashes, we suggest following the steps on this article:
Troubleshoot blue screen errors. Kindly choose the appropriate answer to the category
"When did you get the error?".

We'll wait for your response on this matter.
