Quick update:
Played yesterday for 5 hours straight. Like 3 hours without faceit then games on faceit. 0 lags occured, i think that also my game feels smoother after this whole journey. Nothing is sure yet, but for now it seems that the problem is gone. But dont u have any idea why my monitors sometimes go black for like 2 sec? Then screen appears and everything is all right. Is it DisplayPort cable problem or port in my GPU?

is that in game or outside?

This might not help (or might be for other black screen problems)

is the game running at native resolution for the monitors?

Check the power settings:
1. Right-click the Start button on the far left side of the taskbar and select Power 2. Options from the expanded menu.
3. Tap the Additional power settings button below Related settings.
4. Find the power plan currently in use and tap the Change plan settings button next to it.
5. Change Turn off the display and Put the computer to sleep to never, and tap the Save changes button.
6. Go back to the Power Options window, find and click Choose what the power buttons do in the left panel.
7. First click the Change settings that are currently unavailable button, uncheck the 8. Turn on fast start-up (recommended) checkbox, and click the Save changes button.

Did you update your GPU drivers like I suggested?

Unlikely to be cable if its both monitors turning off at same time.

So its very random sometimes when im on pulpit doing some excel things, sometimes when i open the opera and watch some youtube and sometimes in games. But I only play cs2 with non native resolution. But in league of legends for example it sometimes went black also but i play native there.

You mean this what u have written me lately? try running ddu in safe mode, uninstall the GPU drivers, boot into normal and install latest drivers https://forums.pcgamer.com/threads/how-to-clean-install-new-gpu-drivers.146925/ didnt do it but will do now.
 
With games I can understand some black screens like when you first load games, but it shouldn't do it in excel or browsers.
switching from native to non likely causes at least one when it swaps

  1. drivers might help.
  2. The power settings in my above post could as well.
  3. I don't think its the cables as it happens on both monitors. You have to be unlucky to get two bad cables.
  4. I assume PC isn't overheating
  5. Malware can cause black screens too, try running malwarebytes and see if you have anything.

Curious, does it happen with only one monitor attached?
what resolutions are you running at?

thermaltake smart bm3 750w

seems a fairly okay PSU.

I did all you have told me yesterday (ddu and install fresh drivers, checked the power setting) but now i was running my pc for like 2 hours. Was in lobby i home screen in league of legends - not in the game - on my main monitor 1920x1080 244hz. And was writing to my friends on discord - which i have on the other screen. And only my main one with league went black for 2 sec.
 
So is it the same monitor each time? I would swap cables and see if it turns other monitor off, if you can.
check monitor power and data cables are attached right

It turning off on one while you talk on the other sure makes me wonder. PC keeps running as if nothing happened.

what make/model is the 1080p screen? Your main one.

So my main one is plugged by the display port and the second one by hdmi. Cables are attached good i checked it, changed the cable but the problem still occurs. My main monitor is
VIEWSONIC XG2431 . Now it occured again. I had the windows screen when u are supposed to write a pin to get into system and the screen again went black.
 
When you say the same thing happened, Is it the same monitor each time or is does it happen on a specific connection - HDMI or DP?

I realise its the primary connection. I did see one person with monitor saying it only black screens when it is primary.

One person had same problem with same monitor and reinstall of windows fixed it - link

The most important step is before the install, make sure you saved everything you need somewhere else so you don't lose anything. Once you clean install it will be too late. Cleans aren't so bad if you ready for them.. just suck if they are a surprise.

Drivers:
Windows 11 is pretty good, it will try to get any drivers for any hardware you have installed.
it should get your sound, and lan drivers. Realtek are pretty standard

I would grab the Chipset drivers from AMD again, I linked them on page 1 of this thread already

Depending on where you get your GPU drivers from, you probably also need the Nvidia installer. Though as I said, windows will have drivers for it.

this might help with the clean install:

About only things it might not get is any additional software for mice/keyboards. Depends what you have, I would have to get some for my mouse.


Its something I need to do in a few months when I get new PC. Make a list of installed programs and make sure I have everything I need written down.
Steam games are easy, you can reuse the old folders on a new install. I generally have those on another ssd so I just point the client at the old folder and it doesn't need to download everything again.
Shame Xbox games doesn't work like that.

Thank you so much for help. I will save important files and look what apps are needed for me.

Its the one thing I haven't done on this PC. Installed windows 10, updated to 11. 5 years later on same install.
Had a few problems I had to fix along way but compared to old windows, 11 is really hard to break (unless you try).

Yours is strange.

Have you tried monitor on another PC? If it happens on 2 its not PC, I would try that before reinstalling windows... I have had problems in the past where we tried everything and only after a clean install didn't fix it, it turned out to be hardware. though in my case, it was a mouse and a set of speakers to blame... i don't think that is cause here. Still worth checking.
