Disable the auto restart when the system crashes and give us the full details of the 'stop error' code from the BSOD.
To disable auto restart:
Open 'System Properties' via Start > Control Panel > Performance and Maintenance > System
[ System Properties may also be opened using the WinKey+Pause key combination ]
Select the 'Advanced' tab and then click Settings in the 'Startup and Recovery' section.
In System Failure section, clear the checkbox next to 'Automatically Restart'
Click OK and OK to exit.
Now the next time you get a BSOD, your system will not restart automatically giving you plenty of time to write down the error code as listed, for us to look at!
