AMD AM4 system instability

A bit of background, I built myself an AMD socket AM4 system back around January of this year (if I remember correctly).

And ever since I built it pretty much, it has had this odd quirk where it will randomly lock up or crash either when going into screen saver mode, or when coming back to the desktop when coming back out of screen saver mode.

This issue is persistent across multiple OS reinstalls, multiple different versions of Windows 10 and multiple different pieces of hardware.

Original Build Specs:
AMD Ryzen 5 3600X
Noctua NH-U12S heatsink
Gigabyte X570 Aorus Ultra Gaming Motherboard
2x8GB G.SKILL F4-3600C16D-16GTZR TridentZ RGB
EVGA GTX 1080 FTW3
Samsung 970 Evo 1TB OS Drive
Corsair RM650i PSU

After a few months of fighting with these issues I started swapping hardware, found a Ryzen 7 3800X online for a good price and put that in (I didn't buy it for this actually, had bought it for another build that I didn't move forward with). Issues continued. Then bought another Gigabyte X570 Aorus Ultra motherboard, issues continued. Reinstalled OS with the new motherboard and the 3800X in, issues continued. Swapped out original RAM sticks for a kit of F4-3200C14D-16GFX, issues continued. Tried probably 4-5 different video driver versions with no change. In addition to the GTX 1080 I also tried a couple of 1660 Supers and a 2060 Super, with no change in symptoms. Swapped out the RM650i power supply for an RM750i power supply (stupid, because my rig could possibly be under supplied with power, it only drew 350-375W under load at most while gaming), with no change. Bought a third kit of RAM at some point and tried that, and you guessed it this made no difference either.

Finally, I bought another board from a different manufacturer because after swapping out everything else and finding posts on other forums from users complaining of issues with Gigabyte and/or Aorus motherboards being unstable I was convinced that the motherboard must be the issue. Got myself an Asus ROG Crosshair VIII Hero and a new SSD, a Samsung 970 Evo Plus 1TB drive to do a completely fresh install of the OS. Within a few hours of the fresh install of Windows 10 and reinstalling "most" of my programs, it proceeds to lock up again after I'd walked out of the room to get something in the kitchen.

Next, came to the conclusion that the video card was the issue and tried it with an RTX 3070. Which, while helping my frame rates in games, made no difference to my random lockups when in screen saver mode.

I may have forgotten to mention this, but I can game on this system for hours on end with no obvious issues or instabilities. But will randomly crash or lock up once or twice a week when entering or exiting screen save mode. Temps are reasonable all the time, power draw on the system even at its highest-end/highest-power config maxes out at 425W while gaming. The longest I've managed to go without a crash is maybe two weeks. I've swapped hardware on this computer so often it's barely had time to get dusty, and the thermal paste certainly hasn't had time to break-down.

I am well and truly stumped, I have replaced every part of this computer, save for the case, and it is still unstable. I've basically re-built it three times now probably. I've even considered whether to cut my losses and just build an Intel-based computer instead, though that may not make sense at present with Intel rumored to finally be moving on with a new platform that hopefully won't still be 14nm+++++ with potentially DDR5 memory.

I had made a similar post to this a few months back, but then the site had to do a rollback the next day for some reason and my thread was lost as a result. I well and truly hope that I don't have to type all of this out a THIRD time, this time I waited until I was annoyed enough to retype it again (since it took me over 30 mins to type out the first time and I had no copy of it saved on my computer). This time I saved what I posted here in a file, if they roll back the site again, at least I have a copy of the original post to re-post it if I have to.

It's not a hardware issue. It is OS related and how it manipulates the power saving stuff when you go in or out of sleep mode or screen saver. Try changing to a performance power plan and see if that makes a difference.

I've tried Power saver, Balanced, and High performance power plans, they all resulted in a system crash or hang. High performance unfortunately results in a hotter-running system, but I kind of expected that.

It was stable for about a week on High performance, then one night I left my computer to go put some clothes in the dryer. Came back, and found my computer had locked up while I was in the laundry room. :bang head

I don't understand it really, my old PC never had this problem and it used the same PSU and GPU. Maybe it's just an AMD-specific issue, as my last two builds were Intel-based (Z97 and G33 chipsets) and neither had this issue? Although another difference is that I'm on NVMe storage now, and my last build was a 2.5" SATA SSD.
