I was just browsing on my pc on youtube when my display went black but still showed as if it was getting signal just a black screen. and then my keyboard and mouse started flashing. like if something was loose and you jiggle a cord to see the light flickering. and it repeats this. so I turn off my pc and then boot it up only to have signal to my monitor from my pc but the screen is always black. and my mouse and keyboard will randomly turn on for less than second. I would normally troubleshoot this myself no problem. but I am at a loss as to what is happening. :(
 
Solution
looks like your rig having power supply issues. to see if it is the power supply use a volt meter and check the voltage at the 24 pin connector. or you can pull the gpu and see if pc post with onboard video.
