BSOD while/after Shutting down pc

Hi hoping someone can give me some advice on why this has just happened to me while shutting down my PC. I shut it down as normal and got a bluescreen right after. it restarted and gave me a message "Windows Has recovered from an unexpected shutdown" I have a feeling it might be my USB netgear adapter because it started making some weird noises after the restart. and received this error code;

Please can anyone give me any advice? thanks

Run an sfc/scannow command in an elevated command prompt. If errors are found, run it twice more with each scan followed by a reboot.

Boot into http://www.sevenforums.com/tutorials/666-advanced-boot-options.html and choose the Last Known Good Configuration option. This should start Windows with the last known registry and driver options that worked.

Enable Driver Verifier. However before you do, it is advised that you create a system restore point and backup first.
