OK...I am now willing to bet that this is a VR related issue. There do not seem to be any problems until I plug in my headset and run Windows Mixed Reality. I do not know if it is a GPU or a PSU issue, but it has to be one of the two and it is triggered by the VR Headset and/or WMR.

Silly questions, but worth asking:

1) what VR headset do you have, and what type of cable does it use?
2) where does the VR headset cable connect to ? (assuming to the GPU)
3) what type of PSU do you have and what is its max output?
4) do you have another old spare GPU that you can test with ?

1. Reverb G2, display port and usb-c
2. The GPU
3. EVGA 850 80+ Bronze 850w.
4. No. But this is the second one that has been in the machine.

Some people in other forums have been offended that the retailer would put such a budget psu into a high end system like this one, but 850w should be more than sufficient.

Seems like you almost have this problem nipped in the bud. However before I saw that you now think the issue is vr related I was thinking about motherboard BIOS versions and the speed and type of pci-e card slot you are using. Now that you think it is vr related. Does the vr device plug into a usb port and if so what controller. The vr device does not use the same bus, I doubt it. But perhaps see if you can change to a usb port on a different controller if you have two controllers on your mobo? Also chipset drivers for the motherboard usb chipsets?
But yeah it would make sense that the gpu and vr might fight each other given they are both after showing the same data. Perhaps their is an in game setting that specifies what controller should be given control.

I know you have already played around worth video drivers etc.

I agree, I don't think your PSU model or output/rating is the problem. That seems more than enough for whatever's in your system.  I have a friend who's running VR on an older Intel based board/cpu with a GTX 1650, although it's the Steam VR.  I haven't compared each VR offering's specs, so I can't really compare.  We've run VR system demos at work with high end Dell offerings, so I'm pretty sure your power output is fine.

You seem to have isolated the problem to be focused around connecting the VR device, which uses both Displayport & USB-C (both can carry power).  I think one thing that might be suspect might be the motherboard and how the VR is connecting/working with the hubs.   

I googled a bit about "msi b550-a pro and hp reberb g2" and found quite a bit of threads about issues.  Here's one, but you can find the rest simply by searching what I searched in the double quotes:

https://forums.flightsimulator.com/t/hp-reverb-g2-vr-headset-bad-news-for-amd-motherboard-users-error-code-1-8/338937

AMD did announced they provided BIOS updates for intermittent USB connectivity issues recently
https://www.techpowerup.com/279634/amd-fixes-intermittent-usb-connectivity-issues-on-500-series-chipsets-bios-update-arrives-in-april?cp=2

Now, before going further I would check what revision of the MSI AMI BIOS you have loaded right now and compare with their website's support section.  If too far back, it may be worth trying to flash the BIOS to the latest offering.  BIOS updates these days have come a long way and are much easier to perform than they were years ago.  I have an Asus x570 but MSI's BIOS update offering for their B550 should be something similar.

^all very interesting about the mobo issues with reverb g2. However, the problems reported in that thread are very different than my own. Not sure if it is the same, but I will mention it to tech support. I will also try using the usb adaptor instead of plugging the usb-c directly into the gpu, just to see what happens and to see if I can further narrow the issue.

I remember I had a new PC many years ago in 2011 that gave me multiple BSOD every day.

It took me a month before I found the problem : the anti virus program I had back then (ZoneAlarm) didn't disable Windows Defender so both were active at the same time.
When they checked the same file at exactly the same moment : BSOD.

I'm just telling this to show that so many things can go wrong with a PC and that often you need a bit of luck to find the solution.

I switched to AVG and the crashes were gone forever.

Interesting...using the USB adapter, the computer doesn't detect the HMD at all. That could be the MOBO issue?

Pete reminded me of another thing you could do. Check for BSOD (blue screen of death) dumps after the reboot and analyse the dump to see what exactly was in memory at the time things died. I just wonder whether your reboots produce BSOD memory dump logs.

Does it matter that I have not had a single BSOD? I guess technically, they are GSODs.  I get a green screen followed by a loss of monitor signal, rarely a crash or reboot. I have to physically power off and power on again in order to eventually get to the windows recovery screen where I can boot into safe mode.

Oh I see. I assumed the reboot was involuntary after the green screen. If it was involuntary their is more of a chance a BSOD memory dump record would be left. I have never seen a green screen, so that may just not be showing the BSOD. Green screen might be a VR thing.

Upon doing a very cursory google most people seem to think green screen indicates a desync between picture source and destination.

I wonder if it is the display port cable. There are definitely different types of display port cables. I wonder if VR needs some insane bitrates.

Bandwidth Certification Levels
DisplayPort cables are primarily categorised by their bandwidth certification level. This table outlines the different certifications in more detail:

Transmission Mode   Bandwidth (Gbit/s)   Minimum Cable Certification Needed
RBR (Reduced Bit Rate)   6.48   RBR
HBR (High Bit Rate)   10.8   Standard
HBR2 (High Bit Rate 2)   21.6   Standard
HBR3 (High Bit Rate 3)   32.4   DP8K
UHBR 10 (Ultra High Bit Rate 10)   40   DP8K

All I know is that the VR headset worked fine with my 2080ti.

I just had the most outrageous discussion with HP Technical Support. I actually need to collect myself before I post about it.

The conversation went something like this:

Me: Good afternoon. I have a Reverb G2 and I have been having major problems getting it to run properly with my new system which has an AMD Ryzen™ 9 5900X 3.7GHz 12-Core, MSI B550-A PRO - ATX and AMD Radeon™ RX 6900 XT, 16GB of dedicated GDDR6. I've heard some G2's have had compatibility issues with AMD based systems and that new cords have been issued.
HP: No. I haven't heard anything about that. Did you check the minimum requirements?
Me: Yes. This system far exceeds the minimum requirements for VR <said in total disbelief>. When I plug the headset into the new system, I get a green screen, the display loses signal and the display driver is corrupted, requiring me to reboot in safe mode, run DDU and reinstall the drivers. Do you have anything to suggest in terms of troubleshooting?
HP:  The headset is probably not compatible with AMD.
Me: Excuse me, this is technical support, right?
HP: Yes.
Me: Are you telling me that the HP Reverb G2 is not compatible with AMD components? I find that shocking and incredibly hard to believe.
HP: Well, I'm just saying that because it just doesn't work with your new system, and since it worked with the old...
Me: I'm sorry. Do you have anything useful of a technical nature to suggest in order to troubleshoot this problem?
HP: <click>
Me: Hello?
HP: <dial tone>

I'm still trying to wrap my head around this.
