Asus PRIME B450M-A II with RYZEN 3 3200G BSOD A5

Hi, wasted allready 12h, didnt get a WIN7 installation.

Is it possible to install WIN7 on this board CPU combination?

I tried:
1. Install virgin WIN7 from DVD -> BSOD ACPI Error Code A5 after the loading files screen before installation menu

2. Downloaded the GPU drivers from canonkong-thread, integrated with "Integrate7" in ISO -> BSOD ACPI Error Code A5 after the loading files screen before installation menu

3. Downloaded pure drivers for mainboard from canonkong-thread, tried to integrate with "Integrate7" but "Integrate7" failed and didnt complete the ISO

What else can i do?
Should i do a BIOS update? Is there a better Tool then Integrate7 with guide?

Thanks in advance
