A Guide to the CNSS_FILE_SYSTEM_FILTER Blue Screen of Death Error

The CNSS_FILE_SYSTEM_FILTER BSOD (Blue Screen of Death) error may appear during the initialization process for Windows Vista, XP, and 2000, and Windows 7 and 8.

This error usually occurs when the nonpaged pool memory is full. It is also triggered by events when the available nonpaged pool memory is low and two different kernel-mode drivers compete for its use.

You can also resolve this BSOD error by running a memory check.

Replace defective memory and ensure that it resides in the correct slot in the motherboard.
