However, depending on the root cause, the solutions may differ. I’ve covered all the scenarios in this guide.

What Is dxgmms2.sys in Windows 11?

dxgmms2.sys is a Blue Screen of Death error caused by the absence or corruption of the dxgmms2.sys system file. It’s usually accompanied by messages like SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, SYSTEM_SERVICE_EXCEPTION, or DRIVER_IRQL_NOT_LESS_OR_EQUAL.

What Causes dxgmms2.sys?

The main cause of this error is the absence of the dxgmms2.sys file from the system. However, it could also happen because of:
