Q: my mac will not screen shot using shift command 4 anymore
My Mac Pro Laptop will not screenshot using shift command 4 anymore, and also occasionally my computer will act as if you are holding down the side bar and the screen moves up when I am not touching it. My computer will also make that beeping noise (like the one you get when it is warning you) or when you can't open something up.
MacBook Pro with Retina display, OS X El Capitan (10.11.6)

Is the noise three beeps -- that could indicate defective RAM.
Try some of the different ways of taking screenshots to see if any work. How to take a screenshot on your Mac - Apple Support
Not sure what you mean by "holding down the sidebar."
You might try a NVRAM reset. How to Reset NVRAM on your Mac - Apple Support
