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.
OPTION 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.
>Undo the change you made and test again for the STOP Error. Depending on what it was that changed, some solutions might include:
>Starting up using Last Known Good Configuration to undo recent registry and driver changes.
OPTION 2
>Use System Restore to undo recent system changes.
OPTION 3
>Roll back the device driver to a version prior to your driver update.
OPTION 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.
