My screen keeps changing contrast on its own.

Have you checked under Settings >> Colours to make sure "high contrast" is not selected?

High contrast is turned off.

Can you post the brand and model name or number of the PSU and RAM.

RAM is Team Group T-Force Xcalibur DDR4 4000 CL18.

PSU is Cooler Master MWE Gold 850 V2.

The RAM is not appropriate for your CPU, AMD state here up to 3200MHz/MT/s and if you have DOCP/EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

You should also make sure that the Windows Power Plan is set to Balanced and not High Performance or Ryzen Balanced.

You have a high end rig but a PSU that is rated as – Tier B • Mid-range

You have a couple of major issues going on but before elaborating can I ask;

Why you have not disabled XMP and why is the Windows Power Plan set to High Performance when it was advised that it should be Balanced.

Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues coupled with the number of drives and a not very good PSU such as the one that you have things will get hotter and weaker the more that you use the PC and if not careful something may go bang.

XMP was not enabled. Just regular overclock on RAM to 3600 MHz and CPU to 4.7 GHz.

I disabled all overclocks and the issue persists, as I assumed it would. And no part ever overheats, otherwise I would not overclock them. The GPU is even undervolted.

I might have not explained it correctly, but when I said that it happens when Windows boots, I meant that it happens when I get into the desktop.

Hi there,

I uninstalled AMD Adrenalin and the issue stopped while it was gone. Once I installed it again, the issue returned. The issue is the GPU driver. I'll have to contact AMD about this.

Take care.

Think that you will find that the core issue lays elsewhere but thanks for the follow up in any event.

I'll have to contact AMD about this.

 

Good luck with that.

I did contact AMD and they responded, but I ended up just reinstalling Windows 10 and the issue is gone.

Doesn`t look like you were overwhelmed with their offers of help, more like a total lack of it.

A clean install helps on occasion but any underlaying issue/s will always come back, it is a case of wait and see if your other present problems trigger the recent behaviour, one of your previous problems is addressed below; 

Whatever you do, stick with Windows Defender for your AV protection, one of if not the main cause of your troubles was you having two AV pograms unning at the same time, not just bad but very risky as well.

There's diverging opinions about that, but I'll just use Windows Defender for now.

Using 2 AV's at the same time is never a good idea.

By all means have a second program available to run stand alone scans from time to time that's a good idea. But 2 AV's constantly monitoring your system will cause conflicts.
