Question Need Help. PC Shuts down randomly.

[Irfan.ahmed]

Greetings,

I bought and assembled myself a new gaming pc in 2020. I've been using it for gaming and as a workstation since then. From past few days, my PC is shutting down randomly. I have to power off the UPS or turn off PSU and on again to start the PC again. I am not sure what's happening.

The issue started with PC powering off automatically when I plug in any usb stick in usb 3.1 port in front.

Now it randomly shuts down unexpectedly, i can see RGB lights are ON behind mother board and also Cabinet's power button RGB is ON. It does nothing when I press.

I am not sure if the PSU is faulty here or just some software issue.

Here's my System Specs:

AMD Ryzen 3700x
Zotac GeForce RTX 2070 Super Video Card
Asus x570 Plus Tuf Gaming MB
Cooler Master MWE 650 Gold Fully Modular PSU
Deepcool Castle 360 RGB V2 Cooler
Crucial P1 M.2 SSD 1TB
G.Skills Ripjaws 32GB x 2 Memory

I tried reinstalling USB drivers,
I tried uninstalling GPU drivers using DDU and clean reinstall.

Please advice me what should I do next.

PC is shutting down randomly.

just one second on, next second black screen with no power?

or actually crashing with blue screen or other info?

what should I do next?

1st i would keep an eye on system temperatures while it is running up to a crash.

Thanks for the reply.

It's very random.

I am not even playing any game. I was copying some files from one drive to another. It got shutdown.

Sometimes just watching videos on YouTube. Or just simply coding. It shuts down automatically.

And, Sometimes when I power on. It doesn't boot the OS. It shuts down automatically after a second or two.

Any random instant shutdowns (not blue screen of death) is usually a power supply issue.

as i stated,

Temperatures are normal. CPU went as high as 50. GPU below 30.

I tried resetting the PC and reinstalling windows. Now i am not able to complete one software install properly.

Today I was installing GeForce experience software and was monitoring the system temperatures. All temperatures were normal. But system shutdown between the install process..

Happened twice.

Is there anything to do with thermal paste? Should I reapply thermal paste. Because I haven't applied since I assembled the PC. And i am using cooler master All in One liquid cooler.

Thanks for the reply mate.

I don't have a spare PSU to verify this. Any other way I can confirm if this is PSU problem?

Also, Is there anything to do with thermal paste? Should I reapply thermal paste. Because I haven't applied since I assembled the PC. And i am using cooler master All in One liquid cooler.

As I said, everything points to the power supply.
Cheapest way to test this is ...with another power supply.
