Hello, today I encountered this problem and managed to resolve it. It might have been caused by updating the BIOS yesterday due to a DRAM post light concern involving four sticks. I hope my solution can assist others facing similar issues. Problem summary: My GPU would disconnect through software means, likely related to a PCI Bus issue. Previous steps included: - Adjusting settings; - Warnings about PCI Bus reconfiguration from Windows 10; - Adrenaline not functioning properly even after downloading the correct GPU model; - Multiple Event 225 Kernel-PnP entries in Computer Management, indicating what appears to be "expulsion" of my GPU. PC Build details: - MSI B550-A Pro (last BIOS version 8-2022) - R5 5600X - 4x 8GB Corsair Vengeance 3600 MHz - Sapphire Pulse Vega 56 - EVGA 850W 80+ Gold solution chain/Troubleshooting: 1) Clean and reinstall Adrenaline; 2) Verify events in Computer Management – insufficient data to fix due to persistent multiple Event 225 Kernel-PnP and PCI Bus warnings. 3) In BIOS, set PCI_E1 [Gen3]>[Auto] and check again. No more Event 225 Kernel-PnP or PCI Bus warnings appeared afterward. Further steps: Turned on Smart Access Memory following proper procedure; after that, the Event 225 Kernel-PnP no longer showed up. I also ran Adrenaline Stress Test for ten minutes without any issues.
