Windows 7: Remote Shutdown After BlueScreen?

I have a computer that I remotely connect. The computer has a blue screen problem. It gets the blue screen and restarts, but after restarting, it doesn't go to the boot screen; it just hangs up with a black screen and a flashing underscore. To restart the computer, you need to shut it down first and then turn it on.
I am not close the computer physically and the person near the computer cannot fix the blue screen problem. So, fixing the blue screen problem is not a choice at the moment (And actually I tried remotely to find the problem when the person is there; but with no luck).
The thing is every time, the computer has the blue screen problem; I have to wait that person to come home and turn the computer off and then turn it on again so that I can remotely connect again.

My question is;
Is there any way to remotely shut down a computer when the computer has the blue screen (without restart) or when a computer hangs with the black screen after the restart of blue screen.
I cannot think of how could it be done, but I still wanted to ask this on my favorite place on the Internet.
I mean when the operating system is on, it is possible; a computer can be woken up by ethernet (I don't know about wireless); but I do not know of a way to remotely shut down a computer (so that I can wake it up by using ethernet, or if possible wireless) when it is hanging at black screen.
Thanks.
