Monitor

Something fucked up is going on with my PC. The monitor randomly goes into power saving mode and the computer freezes almost instantly after that. Everything is connected correctly and I think I have no power issues. I have noticed that anytime I bump into my desk or cause some vibrations on the desk this happens. Alos while playing games or HD videos.

Anyone can point me as to what my problem may be?

I WONDER

How the fuck can this be anything but a loose connection somewhere, dipshit?
