Cant really figure this one out. Unless I already figured it out and its the GPU.

I have a build I made in 2017, CPU: AMD Ryzen 5 1600 GPU: Radeon RX 580 Black Memory: GSkill memory cards DDR4-3000 8GB MOBO: ASRock AB 350M Pro4 Power: 550w CX 550M HDD: Seagate 2 tb firecuda

Has been giving me problems in the past year.

I can put in 3 memory cards but the 4th causes stability issues, could not figure it out so I just left it at 24 gb and am fine with that.

Then I had some issues with the HD and had to reinstall the windows 10 os, thats fixed it but I am worried about HD health but so far nothing that seems to indicate it, other than the current problem. I also had an accident with the CPU, where I dropped it and bent 2 pins, this happened a year ago. The pins were straightened and reinstalled back into the mobo, with no issues it seems.

GPU, cant games causes it to shut down. Tried reinstalling the drivers, did not work. I did not reverse the updates.

When I wake up my pc from sleep, there is a brief half second or less of static snow on the main screen. When watching videos, it sometimes conks out when dual screening a videogame, causing the whole video to be janky/filled with artifacts and the UI gets bugged in the player, such as Amazon Prime. The game plays and sometimes hangs, with a crash when the GPU warms up. It crashed to blue twice so far, giving me an AMDKMDAG.SYS error. Which says it could be driver, gpu, cpu or memory issue.

The issue is that I am not sure if its a hardware issue, where can I pinpoint it and fix it without having to do a swap and test. Or it is a software issue that I would need to replace the HDD. As any of the devices above could be the source of the issue. Right now I am leaning towards a GPU issue as 1 monitor seems to work out fine however I really prefer 2 monitors.

The biggest thing is that it doesn't always crash, sometimes it does fine for hours at a time.
