Occasional black screen crashes on a brand new PC and Windows 10 - Event Viewer full of errors

My system: (Brand new):
Monitor: Acer Nitro XV272UP
Motherboard: Asus TUF x570 plus with Wi Fi updated to newest bios 1.2
CPU: Ryzen 3700X
GPU: Sapphire Pulse 5700 XT (19.9.2 - Recommended version)
PSU: Corsair RMx 650 W
Windows 10 (up to date)

The Problem:
So this happens completely randomly (mostly while I'm in desktop) my screen goes black and my PC is still running but unresponsive. After like half a minute I can start hearing my clicks or apps but the screen remains black. After the initial black screen everything freezes but after a while the PC resumes (at least the audio and the controls) but the monitor has no signal. This hasn't happened once while I was gaming, only when I'm idle, browsing or watching something. So I went to check with the event viewer and there are multiple critical level and error level issues. I'll list some of them.

One example of my Event viewer

Local Launch permission for the COM Server application with CLSID-event4.png


What I've tried:

1. Updating all drivers to recommended versions (including bios). Had no effect at all.
2. Updating drivers with Armory Case from Asus. No effect
3. Stress testing CPU and GPU - everything is fine, the noise and the temps are normal. I used furmark and prime95
4. Unplugging the HDMI cable and plugging it back in. I want to note that my monitor came with only 1 HDMI cable and my graphics card has only one slot that supports "that" type of a HDMI cable. So basically I couldn't connect anything wrong cause there is only one way of doing it
5. Turning sleep mode off and on. This had no effect. The PC and the monitor both wake up normally from sleep mode
6. Ran SMART for my SSD - SSD was marked as "good"
7. Unable to run windows repair because "access is denied"

It's really frustrating that this is happening like 3 days after I've built my PC. I don't even know where to start looking for the cause of this problem. How can I fix my drivers when they are up to date?


Any ideas and suggestions would be appreciated.
