npfs.sys error (unable to boot)

Windows keeps shutting every time I boot up. I get the blue screen and something about npfs.sys. I cannot restore or use sfc.

I have tried the following using "System Recovery Options":

STARTUP REPAIR
Startup Repair could not detect a problem.

SYSTEM RESTORE
System restore did not complete successfully. Details: System restore failed due to an unspecified error. The file or directory is corrupted and unreadable. (0x80070570)

WINDOWS MEMORY DIAGNOSTIC TOOL
A problem is preventing Windows from checking for memory problems during startup.
