Blue Screen of Deaths (BSODs) are common events in Windows operating systems and Windows 7 is not an exception. Such instances usually lead to data inaccessibility and ask for Windows Data Recovery help. Windows BSODs primarily occur due to errors in memory modules, hardware issues, operating system errors, and many similar causes. One of such BSODs is discussed further.

For instance, a Windows 7 might prompt the following blue screen error:

“Page_Fault_In_Nonpaged_Area

Stop: 0×00000050 (0xE41B0E15, 0×00000000, 0xBF88CD88, 00000001)”

The error might prevent Windows 7 from booting.

A newly installed hardware that might be failed, generally RAM
Defective main memory, video RAM, L2 RAM cache
An updated driver
Buggy system service
Incompatible antivirus software
