Description of Original Problem: 1 out of my 2 AMD R9 270A GPUs (not to be confused with R9 270) has an issue utilizing any AMD driver that I install for it. Whenever I install a new driver for my 2 GPU’s, the GPU in PCI bus 6 is intolerant of the driver ONLY once it starts the display driver install (endless backlit-black screen, hard drive stops spinning), and I need to disable the device in PCI bus 6 while in safe mode in order to have a working computer. It’s not an exclusive issue for the GPU in PCI bus 6 because if I swap the spots of GPUs, the issue still prevails in whatever GPU is in PCI bus 6. The bus isn’t broken though, since my display is plugged into whatever GPU is in PCI bus 6, and it works until I install a driver.
Troubleshooting: In order to have the computer working, I need to boot into safemode and disable the graphics card driver for the GPU in serial bus 6 in order to have the computer functional. At that point, everything works and I do have 1 working video card, but I’d much prefer to have both enabled and working so I can use AMD Crossfire.
PCI bus 6 is physically clean, it is enabled in BIOS, and the video card in it is correctly inserted.
My attempted download process for each and every AMD driver is as follows:
0.) Use DDU (if I had any previous drivers)
1.) Immediately turn off driver updates recommended by windows
2.) Disable fast startup and hibernation mode
3.) Download all win10-compatible drivers for my Gigabyte motherboard (https://www.gigabyte.com/Motherboard/GA-970A-DS3P-rev-2x/support#support-dl-driver)
4.) Download 990x chipset driver from AMD site (https://www.amd.com/en/support/chipsets/amd-9-series-chipsets/990x)
5.) Download AMD Radeon Adrenaline 20.9.1 (last recommended driver) from AMD site (https://www.amd.com/en/support/previous-drivers/graphics/amd-radeon-r9-series/amd-radeon-r9-200-seri...)
6.) Disconnect my internet
7.) Download all win10-compatible drivers that I downloaded
8.) Download 990x chipset driver I downloaded
9.) Download AMD Radeon Adrenaline 20.9.1
For both Adrenaline AND all previous drivers I tried (I went as far back as version 14’s for Win10 64 bit), my PC would ALWAYS either completely freeze, or the screen would go backlit-black at some level of progress for the AMD display driver installation. No other step was an issue.
Any help appreciated. Thanks guys!
