I have had a friend bring me their PC with this error also, It looks like a piece of software is causing this when The machine is loading in windows. I am not sure if it a type of virus or a program that has installed with errors, or is conflicting with another.
Try booting your machine in safe mode (F8 while booting, after the specs) and uninstall what it could be, then reboot normally.
I am still trying to recover this machine as He and I have no clue what has done it, and he has some dodgyu parttioning software installed!!!!....git!
Hope that helps (if you haven't sorted it yet)
