Question STRANGE pc black screen issue

[Davve95]

So my pc screen is turning black after a while.
Sometimes it can take very long before it happens and sometimes it can happen very fast and I have also seen some strange interruption on the screen when it happened.
More symptoms:

* Failed to boot. First time it happened
(Have not been happening since)
I don't remember exactly, but I think it was s boot loop or something.

* Strange noise in the headphones, when the black screen appears

* I can't do anything at all with the computer example CTRL + ALT + DELETE.
Only thing I can do is to force shut down the computer and if I power it on again it works.
But same issue can appear again.

* PSU did sound strange once. With one of them I had. I had many replaced (see further down)



Things I have been trying:

1. Replacing SSD

2. Replacing ram

3. Trying a brand new motherboard and CPU.

4. Replacing the PSU on warranty.
They didn't found anything at first.
But the problem did still appear, so I sent it back to troubleshooting. They found some issue and sent back a brand new one the same brand and model. Still same issue.
I sent it back once again and they found some issue I bought a completely new brand. Today when I was trying it out the problem still appear.

5. Removing a bad external and internal HDD
and unpluggin other HDDs

6. Updating all drivers

7. Trying another graphics card.

8. Trying another mouse.

9. Fixing cooling related stuff. It got too warm once.

10. Stress test

I have been trying the stuff it in a different order, I was writing it by accident in wrong order.
I really hope someone can find the issue.
I'm going crazy by this when it appears again and again even with everything I have been trying and it does not feel so good having spent so much money on everything...


I really don't hope it is a bad HDD or my graphics card that have been destroying the PSU each time? If that is even possible?
I have not seen any symptoms of bad HDDs of those I have left neither the graphics card.

Computer specs:

PSU - be quiet! Straight Power 12 Platinum 850W
Windows 11 Professional
Gigabyte Z490 UD
32 gb ram
Intel core i5 10400F
Radeon R9 390 Gaming 8gb
2 Samsung SSDs

The pc is built 2015 but have been upgraded
further on too.

Old PSU: Deepcool DQ750

Make sure you're on the latest BIOS version.

As for your mention of swapping the board, did you swap out for a like-for-like board or another make and model motherboard?

Use DDU to remove all GPU drivers(Intel, Nvidia and AMD) in Safe Mode then manually install the latest GPU driver sourced from AMD's support site in an elevated command, i.e, Right click installer>Run as Administrator.

I really don't hope it is a bad HDD or my graphics card that have been destroying the PSU each time? If that is even possible?
You might want to source(borrow, not buy) a discrete GPU to rule out your R9 390 is the root cause of the issue. It's times like this that an non-F SKU processor comes in handy as the iGPU would've told you if the system without the GPU is triggering the same issue.

32 gb ram
Got a link to the ram used? Have you tried with one stick of ram in slot A2?

Is your outlet grounded?

Motherboard and CPU:

ASUS TUF Gaming B550-Plus
AMD Ryzen 7 5700 3.7 GHz 20MB.


Drivers - I have been trying to remove the old drivers and then installing new ones.


Bios - It feels very risky to update, since I guess it can happen while in there. I don't
Want to risk bricking the whole motherboard haha.

Ram - Corsair Vengeance LPX DDR4 3600MHz 32GB

I had some HyperX as my old ones.

I don't remember the full model name.

I can check tomorrow if you need it.


Hm, I don't think so, I will try again tomorrow just in case. I think I have been trying but the wrong slot.

I'm not from an English speaking country, so perhaps Google Translate will do the job if
yoy need to check out the link.

GPU - I'm not fully sure what you meant.
I was testing with a super old graphics card.
That I had laying around.
You want me to borrow another one?
So I can test?


Yes, I have a grounded otulet and the pc power cable is connected straight into the power outlet
