My PC crashes but stays on.

Hello,
Usually, it's me who helps people solve computer problems, but this time I need your help!
Here are the components of my PC:
- Processor: AMD Ryzen 5 2600
- GPU: Radeon RX 570 8Go
- Power Supply: Aero Cool 650 Watt
- Hard Drive: 2 SSD
- Motherboard: Asus Prime 450MA

The problem is quite difficult to explain. Basically, at any time, 2 minutes after starting the PC, whether gaming or not, the PC crashes and the display turns off as if the graphics card crashed (the GPU fans stop) but the PC remains powered with the fans running.
I've done a lot of tests and changed several components to eliminate possibilities.
I first thought Windows might be corrupted, so I reset the OS by wiping Disk C to 0, still the same. Then I thought it might be the power supply, which was a bit old, so I changed it, still the same, so it's not that. In short, the 3 components that could be problematic are: graphics card, processor, or motherboard.
What makes me doubt that it’s not the graphics card is that when I wanted to increase the base frequency of my processor once, the PC crashed immediately.
The thing is, my GPU ran for a few months without the fans working; I had to make them work via the Radeon software when I realized it. The processor, even under stress test, doesn't get that hot, and neither does the GPU when the fans are running.
By the way, when it crashes, I have to restart my PC and reset the GPU settings for the fans to turn on.
My drivers are up to date; I've done several reinstallations of the drivers, etc., but I still can't find the exact cause of the problem.
It can also happen that if I hit the PC with my foot, for example (not particularly hard), the PC crashes.
There you go, I hope you have enough information to potentially identify what the issue might be or to lead me towards a clue to avoid buying a component for nothing.
Thanks!

    Hello,
    in your case, I would have started with the graphics card or even changed the video output on the graphics card since the PC stays on, even for a brief moment, as it crashes even outside of gaming.

      I have 2 screens, one connected via HDMI and the other via DVI, and both go to "no signal" mode when it crashes. When it crashes, the screen freezes and then shows "no signal". I also have serious doubts about the GPU, but I'd like to be sure.

      Well, the thing with the components is that to know where it comes from, you have to change them.

      You have sound working properly after the display loss (if your headset/speakers are plugged into your computer).

      Well, I hope not actually ^^, no the sound doesn't work anymore after the display loss.
      Thanks for your help anyway!

      if you have no sound with the headset plugged into the computer, it doesn't necessarily rule out the graphics card, but it's less certain.
      try to check the Windows logs (search for Windows Event Viewer in the start menu) to see if there are any error messages

      I had checked with a software that analyzed crashes, but it mostly didn't detect the crashes. I'll check it that way too; I hadn't thought of that.
      I reinstalled my processor drivers as well, but it doesn't change anything????

    Hello
    it may seem unrelated, but
    my husband's computer had the same issue, and after several visits to the store, the computer didn't crash there but crashed at home
    we tried everything: unplugging all the USBs and peripherals one by one, testing the disks, testing the RAM
    in the store they (supposedly) tested the BIOS battery which was fine
    we even removed the UPS for a single plug
    nothing worked
    out of desperation, I changed the BIOS battery anyway and since then, miracle, no more crashes, it was probably still good but a bit weak
    so why not give it a try? for the price of a battery...

      you can try.
      interesting and very strange, this problem was solved by changing the battery. Unless the battery change caused a CMOS clear (https://fr.wikihow.com/r%C3%A9initialiser-le-BIOS-de-votre-PC).

      you can also test without the battery, as it is not essential for the computer's operation; it simply serves to save the BIOS settings, the date, the time, and the component management. A CMOS clear via battery or jumper resets all of that (especially the component management).

      Sure! Indeed, that could be a lead, I was trying, thank you for the information!
      I had already done a clear CMOS by removing and reinserting the battery, but why not try putting in a new one indeed.

    Well, I'm bringing the topic up again haha
    But after changing the motherboard, the problem still persists.
    So I have 2 possibilities left, either the GPU or the CPU.
    I'm going to test it with another graphics card to be sure, but since the crashes are random, it's going to be quite annoying.
    That's where things stand.
