ACPI BIOS error causing BSOD on new AMD system

[kneecyclonic]

Hi, I recently built a new system switching from AMD4 to AMD5 and I'm getting a constant ACPI BIOS ERROR BSOD. I’ve updated to the latest BIOS, tried new RAM, and even used just one stick, but the BSOD loop continues.

I attempted to install Windows 11 from a USB, but the blue screen prevents me from accessing the installation process. Can anyone help me resolve this issue?

new system switching from AMD4 to AMD5

In my mind 'new' is not consistent with 'switching' from one CPU to another one since the 2 CPUs are not interchangeable on the motherboard, different number of pins.

AM5 has 1718 contacts on the underside of the CPU, compared to AM4's 1331 pins

try slowing your ram timing one step. other wise check each switch in the bios is set correctly and write all your steps down as you go in an exercise book so if you set somthing incorrectly you know what you did. anso if you have multipul drives check your tryingto install on the correct active drive.
