I've gone through multiple forums trying to troubleshoot my problem. Others have had similar issues, but their solutions haven't worked for me. Hoping someone will be kind enough to help!
I'm using an old Sapphire R9 270X 4GB graphics card (wanted to upgrade to the new RX 6000 series before the great GPU shortage hit!).
My apologies in advance for the long post, I've tried to insert headers to make it easier to read!
AMD Ryzen 5 2600X (no OC)
MSI B450 Gaming Plus motherboard
Corsair Vengeance 16 GB of 2933MHz RAM (8x2 sticks in 1 & 3 slots)
Sapphire AMD/ATI Dual-X R9 270X (4GB) graphics card
Corsair 600W PSU
Samsung 860 EVO 500 GB SATA SSD
1TB 7200 RPM internal HDD
Paired with a 32" LCD TV as a monitor connected via HDMI.
OS - Windows 10 v2004
Graphics driver - Adrenalin 20.9.1
The above configuration was working perfectly until January 2021, when I updated Windows to the 20H2 version.
Issues faced: Driver timeout error (have sent multiple crash logs to AMD via the automated tool)
Affected applications: Everything [Games (Metal Gear Solid V: Phantom Pain, Dishonored, Borderlands 3, etc), Chrome Browser (while watching YouTube, Netflix), MS Word, even a number of times when the system was idling]
My feeble attempts to fix the issue: Updated all drivers & BIOS (including AMD Radeon software and chipset). Rolled back to 20.9.1.
Result: No change, error persisted.
I read every forum discussion I could find, tried everything (DDU, AMD Cleanup Utility, ran the DISM and SFC checks). No change. Then in my desperation, I decided to clean install Windows. BIG mistake.
My attempts to fix the issue so far:
So currently, I'm stuck. It's clearly a driver conflict somewhere, but I don't know enough to solve this on my own anymore! I don't have another system in which I can install the GPU to check if the hardware is faulty, and I can't really go to a friend's place in the current pandemic! I tried a workaround by installing the GPU in the second PCIe x16 slot, but same result.
I know it's an old graphics card, but I don't even have an option of getting a new card with the current inventory shortage.
Once again, my sincere apologies for the loooong post, I hope it's not too troublesome.
