The Memory manager in your computer system creates two dynamically sized memory pools – Paged Pool and NonPaged Pool – that Kernel-mode objects use to allocate system memory. A new device driver installed in your system uses NonPaged pool to fulfill many of its basic requirements. A STOP error message after installing a new device driver primarily occurs due to depletion in the nonPaged pool memory. Two consequences of this error message are unmountable hard drive and inaccessibility of all files and folders saved in your hard drive. An ideal solution to overcome this STOP error message is restoration of data from an updated backup. However, in case of absence of an updated backup or backup falling short of restoring the desired information, data recovery software comes to rescue.

  Consider a practical case, where you receive the below error message after you attempt to start you system after installing a new device driver:

  “stop:0x000000034 (0x000000000005077c,0xfffffa600239f918,0xfffffa600239f2f0,xfffff8000a466ba8)” The value for four parameters in the above error message differs due to systems’ configuration.

  Parameter 1: The first parameter Specifies line number and source file data. Parameter 2: Reserved Parameter 3: Reserved Parameter 4: Reserved

  Once the above error message appears, the data saved on the hard drive becomes inaccessible. In addition, you encounter the same error message each time you try to start your system.

  Cause:

  Few causes for the occurrence of the STOP error message can be:

  Reduction of NonPaged pool memory Corrupt or incompatible device driver Virus infection

  Resolution:

  To resolve the above error message and access the files and folders stored in the hard drive, you will need to take the below measures:

  Add new physical memory to your system Select the Last Known Good Configuration option when you reboot your system If the problem persists, try using the Emergency Repair Disk

  However, if all the above measures fall short to resolve your problem and you still encounter the above error message, then you will need to reinstall Windows. A clean reinstall of Windows erases all the previously saved data from the selected hard drive partition. For complete recovery of lost data from formatted hard drive, you will need to use advanced data recovery application and for corrupted file you need to use file recovery software.
