I'm running into the same issue here.
My board is an ASRock AB350M Pro4.
Had Windows 7 x64 running with an A8 9x and also an Ryzen 1200 with an nivida gfx.
But if i switch to the 2200G i get the same bluescreen message.
I updated my bios to the latest beta bios with the latest agesa code but that did not help.
I'm reinstalling with the ryzen 1200 + nvidia atm, will try to switch cpu's again after i upgradede all drivers to the latest available.
I just installed, the same MB with the the 2400G having the same issue. Infact I get the issue booting up several software programs. Windows 7 install disk, Easus etc. Also can allocate the amount of ram for the GPU side of the 2400G to use. its using 512 MBs or less. Im stuck with wondering if its the CPU or the MB?
Windows 7 cant be installed @ 2200G and 2400G. It is designed for Win10 only
AMD Failed big time
I understand you have to move with the OS, but no you don't get any information about this, too bad.........
The MB. Companies don't explain this in the manuals, even claim support for Windows 7.
that's too bad.
