What can I do if AMDPPM.sys cause the BSoD?

AMDPPM.sys (AMD Primary Processor Module) is a driver to enable internal and external AMD hardware. If the file is corrupted, it can cause systemic problems like the Blue Screen of Death.

There are a couple of things you can do to fix a faulty AMDPPM.sys file, like running an SFC scan (as shown earlier) and resetting your computer’s BIOS.

While we have you, be sure to check out how to fix BSoD Error 777, which is an operating system failure caused by unwarranted changes made to the registry editor.

It’s recommended that you perform an automatic repair to address this issue. Just ensure you have a bootable USB drive for Windows 11 before performing it.
