I built a new PC less than a week ago, and it had been completely stable through long gaming sessions in Apex Legends, Mortal Shell 2, and FC 26 at ultra settings. Today, Apex crashed while compiling shaders with DXGI_ERROR_DEVICE_REMOVED (0x887A0006) and DXGI_ERROR_DEVICE_HUNG. AMD Adrenalin reported a driver timeout, and Windows Reliability Monitor logged repeated LiveKernelEvent 141, 117, and 193 errors.
The system has an MSI PRO X870E-P WIFI motherboard, XFX Mercury RX 9070 XT OC Edition, Ryzen 7 7800X3D, Lian Li 850W Gold PSU, 32GB of G.Skill Flare X5 memory, and a Thermalright Peerless Vision AIO. The GPU passes OCCT with zero errors, including VRAM testing, and temperatures are normal. There is no overclock or undervolt, and Adrenalin tuning has been reset to stock. I also disabled the CPU's integrated graphics, set the PCIe GPU as primary, disabled hybrid graphics, and updated the motherboard BIOS, but the crashes continue when loading Apex and Mortal Shell 2.
The GPU uses three separate PCIe power cables, and all connections appear secure. One unusual symptom is that the AIO's LCD briefly resets to its startup screen for a second or two whenever the graphics driver crashes. Could this be a driver problem, defective GPU, power-delivery issue, motherboard or PCIe instability, or possibly a USB-related system problem? I'm new to troubleshooting this kind of issue and would appreciate suggestions for the next steps.

A good first step would be to use Display Driver Uninstaller in Safe Mode, then install a known-stable older AMD driver rather than simply installing over the current one. One suggested version is 26.5.2. Some users have reported more timeout problems with later 26.6.x and 26.7.x releases, although driver stability can vary between systems. Test the older driver with everything at stock settings before changing multiple other things.
Disabling Adrenalin's issue-detection or crash-detection feature may stop the notification, but it will not necessarily fix the underlying GPU reset. Since the system still crashed after that change, focus on a clean driver removal and testing an older driver. If the problem remains across several driver versions, then hardware, PCIe, power, or broader system stability becomes more likely.

I've been running 26.5.2 on a 9070 XT without any driver timeouts, so it may be worth trying as a comparison. The newest release is still too recent for us to know whether it fixes the issue.
