Solution-
This error is caused by Hardware or Software, so troubleshooting is much important. The below solution will for all versions of Windows i.e. ( Win 10, 8, 8.1, 7, XP etc)

1. The most important Blue Screen of Death troubleshooting step you can take is to ask yourself what you just did before the device stopped working.
   1. Did you just install a new program or a piece of hardware, update a driver, install a Windows update, etc.? If so, there's a very good chance that the change you made caused the BSOD.
   2. Undo the change you made and test again for the STOP Error.
2. Use System Restore to undo recent system changes.
3. Roll back the device driver to a version prior to your driver update.
4. Check that there's enough free space left on the drive Windows is installed on. Blue Screens of Death and other serious issues, like data corruption, can occur if there's not enough free space on your primary partition used for the Windows operating system.

      5.Scan your computer for viruses. Some viruses can cause a Blue Screen of Death, especially ones that infect the master boot record (MBR) or boot sector. 

    Important: Make sure your virus scanning software is completely up to date and that it's configured to scan the MBR and boot sector.

      6. Apply all available Windows service packs and updates. Microsoft regularly releases patches and service packs for their operating systems that may contain fixes for the cause of your BSOD. 

 

Update drivers for your hardware. Most Blue Screens of Death are hardware or driver related, so updated drivers could fix the cause of the STOP error.

      7. Update your BIOS. In some situations, an outdated BIOS could cause a Blue Screen of Death due to certain incompatibilities.
