Maybe a bad GPU?

Now a clean install of Windows 10 

Hello, 
I recently did a Motherboard, CPU, and RAM swap and had an R9 285DD 2GB instead of the MSI card. I then upgraded the GPU to the MSI card and over the course of 30 days I had small issues flaring up that seemed small at first but now for playing any type of game is unusable. At first whenever the pc was sleeping and then I woke it, there would be white snow for a split second when the monitor would come on and then the desktop would pop on and there would be no issues. I would be playing games, Witcher 3, for a couple of weeks and no further issues came up. I then got Far Cry 5 and then I start to have crashing issues. It seemed to resolve after turning off anti-aliasing and when I overclocked the cpu thru Ryzen Master to 3.9 at 1.375v. Now two weeks later any game I play auto crashes after barely 5 minutes of play and sometimes it crashes at the option screens. I had one instance of pc crashing while streaming a movie(white screen). Most of the time it black screens with no response or activity from the mouse. It also green screened after rebooting the pc. 

I didnt do a fresh install of windows at first thinking they are both AMD builds it would be ok.
I then did a reset of my pc and re-install windows 10 thinking the instability i'm seeing is that.
When that didn't work I just did a clean install Win 10 and the display issues are still happening at a higher rate. 

I downloaded a gpu monitor and temps are at 35C and load is not high at all, it does jump around but nothing that I saw thats concerning.

I was just wondering do I just have a bad GPU? Is there an issue with the RX 570 line of GPU's?( I hope not, I just bought an XFX brand RX570 8GB)

Any games I am playing are crashing. Shadow of War I set to its lowest settings and in windowed mode the GPU temp was hitting 67C to 71C when it crashed after two minutes. The GPU load on a small window was immediately at 100% the whole time.

Any ideas?

how did you install the drivers for the gpu? did you get them from AMD's website?

[Fmmarkov]

Yes AMD and also Radeon drivers.

Those symptoms are indicative of a bad CPU overclock or bad GPU. Set your to CPU to stock, if it's still unstable then RMA your GPU.

Well I have been leaving my CPU at stock settings since the issues started to occur. I have purchased an XFX RX570 8gb and I sincerely hope its just this GPU that is the problem and not the RX 500 series Radeon architecture. Regardless the MSI gpu was purchased used and just going to return it for refund. The XFX will be brand new.
