PC turns off when I play games

[Abraxxis]

Hello everyone,

For the past few days my PC started turning off after 5 minutes when I play games.

Here are my specs:

• XFX AMD Radeon RX 590 Fatboy

• AMD Ryzen 7 2700x with a stock Wraith Prism cooler

• HyperX Fury DDR4 16 GB RAM

  -MSI B450 Tomahawk Max

  -600W Cobra Power power supply

• Mid tower, plenty of space, 3 fans on front sucking in, 1 in the back sucking out

• Software and Windows updates are all up to date. Both Radeon Software and Widows recently reinstalled.

• Virus and malware free

Once my PC first turned off I opened it up and cleaned the whole case, fans, heatsink, etc. I cleaned and reapplied the thermal paste and had the same results.

Because I suspected it was my CPU causing the problems I measured the temperatures, it was 50 degrees C idle. I ran AIDA64 stress test and my CPU temperatures would go over 100 degrees in a few minutes, shutting the PC down.

I undervolted my CPU to 1.35V and I removed the side of my case, pointed a house fan directly at it. Idle temperatures are 37-40.

I tried playing a game again and this time it lasted for 2 hours and turned off again. I gave the PC a break for about an hour and tried playing once more, but it just turned off after 5 minutes, like before.

It's hot as balls where I live, over 40 degrees C (100 F) and I don't own an AC.

I have a few questions/concerns:

• Is this solely an overheating problem? I already ordered a new CPU fan, Cooler Master MasterAir MA612. I considered buying liquid cooling but it requires 300W and my power supply wouldn't be able to handle it, and I'm not liquid enough (excuse the pun) to afford both a new cooler and a new power supply at the moment.

• Speaking of which, could my power supply be the issue? I wanted to change it for some time now, but somehow other things always come first. It's by far the oldest part of my PC and the only thing I carried over from my old PC when I built this one a little over 2 years ago.

• Could something else, like GPU be the problem? Going back to the power supply, specs are showing Fatboy requires 500-550W to run optimally. Is my power supply bottlenecking it? Also the GPU gets so hot I can fry eggs on it.

Any thoughts, ideas, solutions?

Thank you!

If your CPU couldn't handle a stress test for a few minutes, then you are most definitely hitting a recurring thermal shutdown. Not being able to have AC with those temperatures isn't doing you any favors. You might want to add another exhaust fan to your system. You'll still have slightly positive pressure, but it'll help get the air through the case.

 

Speaking of... What case do you have? Hopefully not one with a full glass front panel.

Temps were the first thing I thought of, it could be the psu.  But I'm still thinking temps.

I doubt it's your video card, usually issues with gpu will cause blue screens, getting dump from games to desktop, artifacts or just losing video.

 

So you are still getting 50C idle?  What's your gaming temps?

Check event viewer or the memory dumps to see why it turned off?
