Unfortunately no. My solution ended up simply refunding it all via Amazon and buying different parts a month later. I now run a Ryzen 7 2700x with a 2070 Super on an ASUS ROG B450 and have had absolutely zero issues whatsoever. To this day I have absolutely no clue what the issue was. Wish I had a better answer, but the only solution for me was to ditch the 5700 XT in favor of a 2070 Super.

While I know I can RMA it, my last RMA experience with ASUS took several weeks to be resolved. I'm just not interested in wasting that much time after spending this much money. At this point, I've spent so much time and effort that I'd rather just refund everything and move on. Recoup my money, see what I feel like doing in a week. That's pretty much where I am. My current computer (a two-ish year old laptop) is showing it's age, and I've got to have something to keep me going. I don't want to wait for an RMA, only to find out that still hasn't solved the problem. Thanks to all of you for your attempts to help, I genuinely appreciate it. I think at this point, though, it's best I just move on.

At this point the only place I know where to go with it is a UPS store to ship it all back to Amazon for a refund. That's honestly the only option I see left. Something is wrong, but nobody (and I include myself in that) is able to tell what. This literally just defies all knowledge I have of computers. I really appreciate your attempts to help, but this just seems hopeless at this point.

Aaaaand we're back to unsolved, because as I expected, this did NOT solve the problem. I don't know why I thought the solution would be that easy, but it got my hopes up just to dick with me I guess. For whatever reason it worked for two solid hours, before it once again, crashed with no explanation to no power. And now every 10-15 minutes while gaming, same thing. Error log shows nothing but a 6008, once again. I'm just about done with this. I'm giving it another few hours before I start disassembling everything for shipping back to Amazon. I've spent almost 20 hours troubleshooting. This is absurd. Nobody else has this problem with these parts but me, and nobody can explain it. I'm sick of it.

It is very unlikely that a driver update caused this. A full reformat this early would be way overkill. The fact that it only happens while you are gaming and your rig is consuming much more power almost certainly means electrical interference. A driver issue would most likely cause it to happen all the time. Do you have any USB headphones? That would be a good way to test for electrical interference. If you use USB and hear no hum, that points to interference. If you use USB and hear the hum still, that points to software problem. Otherwise, move your audio cable as far away from any power cables/sources as possible. Again, are you using a shielded cable, or something like a cheapo dollar store cable?

Have you changed the audio cable recently? Or moved it closer to your rig? Is it a shielded cable, or something cheap and thin? This sounds like electrical interference.

After nine straight hours of troubleshooting, I finally solved this issue. Tentatively, as I'm going to keep gaming tonight and see if it happens, but I was just able to do a one hour long session of Forza Horizons 4 without any shutdown. It is currently running in the background as I type this and there's no issues so far. This ended up being the key, but the other way around. Removing PCIe 3.0 as an option fixed it. Out of desperation I started just thumbing through the manual for my motherboard and learned that the PCIe_1 slot is "4.0/3.0" while the PCIe_2 slot is "4.0". Had nothing to lose by simply swapping the GPU to the 4.0 only slot. Did so, booted, loaded up Forza and played for an hour straight with no issues. At this point, I don't truly know what the issue is, but it is something to do with swapping between PCIe versions and by removing that option entirely, it is fixed. So far, anyway. Nope, not that easy. Worked for about two hours and then began to experience the same symptoms.

How would I test that? And again, how would gaming for a few minutes trip it when stress testing for over half an hour doesn't? Yeah no. It's all ordered from Amazon. If it comes down to RMAing parts one by one I'm just refunding all of it and going Intel/Nvidia or even buying an Xbox One. Temps as high as 110c is within spec for the 5700 series. I was concerned by that too at first, as Furmark was showing temps as high as 112c, but it's normal.

Error log stuff ended up being total red herrings. I found and disabled whatever the hell Windows Cache Services is, loaded up Forza, and got the same thing. Now the Event Viewer only posts a worthless Event 6008, and no 7000 and 7009, but still gives the same result. Crash after about 3 minutes of playing Forza and no other errors. Of course. At this point, I don't know why I even bothered. I checked BIOS and see none of these as options, but again, I don't see how this can be the issue. Light gaming that puts the GPU at ~90% and the CPU at ~10% shouldn't trigger any protection that both being slammed to 100% for 35 minutes won't cause. Here's the log. I don't see anything useful. Temps and voltages all remain fine right up to the crash. Only oddity I see is that my RAM is apparently clocked much lower than it should be.

Windows is managing that itself, and has a 2944 MB pagefile on C:.

The 6008 is timestamped at the shutdown, not after restarting. The only other errors around the time occur one second later; an Event 7000 and an Event 7009. Both of these are apparently related to Windows Cache Services which is... part of Windows server? I'm digging deeper into this now.

Yes. Every last Windows update is installed.

Honestly, I don't know. The UPS caps out at 350w so it's above that, but how far above I couldn't say. I really highly doubt it's more than 1000w though. I've read those issues as well, but I've tried both HDMI and DislpayPort, and I'm running at 4K 60hz. I thought about this as well and checked the connection, but there's no way this is it. It's a reproducible pattern. This can't be the issue either because the system is able to support a full throttle stress test for 30+ minutes, drawing far more (or at least as much) power than while gaming. I did more digging and I think you're onto something. I've checked everything; the only relevant error is an "unexpected shutdown" with code 6008. According to Microsoft, that means something used the "InitiateSystemShutdownEx function with the force flag". How do I find out what software is sending a shutdown message? What could even be doing that? It's a totally fresh install of Windows.

I am not on the UPS any more. The UPS doesn't have a high enough wattage to handle the PC under load, so I am on a surge protector on a different outlet. The PC stays down after it shuts off.

Yes. This is a fresh install of Windows and each game, and have all been updated.
