The mouse and keyboard work stuck

[asaf]

Why when I plug another monitor into a DVI connection, my mouse and keyboard work stuck. This is characterized by the fact that the mouse does not move smoothly and gets stuck many times. In addition, the keyboard does not pick up all the words and only picks up some. The computer hangs for a moment and returns.
How can I fix the problem?
Many thanks to the helpers.

Could be any number of reasons but without knowing anything about the computer we have zero chance of being able to begin to help I’m afraid.

Can I just make sure that you are not plugging anything in while the computer is connected to the wall socket, you are asking for trouble if you are as that is the quickest way to short out your hardware.

You need to provide information about your computer, is it a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial) if a custom build post the brand and model name or number for the CPU, MB, the RAM (including the amount) add on video card if one is used and the PSU (power supply unit) providing these details will enable folk to better assist you.[/COLOR]
