Microsoft also notes on the bug check page for SYSTEM_SERVICE_EXCEPTION ┬áthat “If a driver that is responsible for the error can be identified, its name is printed on the blue screen…” Indeed, I’ve personally experienced this error with the Windows 10 NTFS file system driver (Ntfs.sys) identified as the culprit. This identification is a mixed blessing, because it does tell you some kind of file system error occurred. That said, one cannot and should not replace OS-level drivers for Windows as one might do for a device driver of some kind.

Cldflt Sys Blue Screen

Blue Screen is a tormenting issue appearing with system crash, hang, and freeze. The error, with the default settings, compels a PC to reboot at once. On several occasions, after the restart, the Blue screen still appears and then you need to step forward to start the repair task. Cldflt.sys is such an error that can be seen in conjunction with different stop codes. These may be System Service Exception, Page Fault In A Nonpaged Area, Kmode Exception Not Handled, System Thread Exception Not Handled, and Kernel Data Inpage. In all cases, the BSOD shows What failed: Cldflt.sys which means the system crashed due to failure of this file.
