I updated my windows 7 desktop computer with an MSI motherboard and an Intel processor. Now my keyboard and mouse is not recognized by the computer.

Mary: Your motherboard has a PS/2 combo port. You could get a PS/2 splitter cable, splitting the port into two ports – a keyboard port and a mouse port. Here is an example of a PS/2 splitter cable: https://www.amazon.com/KEYBOARD-SPLITTER… Then get yourself a PS/2 mouse: https://www.amazon.com/Logitech-M-SBF96-… …and a PS/2 keyboard: https://www.amazon.com/dp/B0075W8C8S/ref… Make sure your computer is powered off when connecting or disconnecting the PS/2 mouse, keyboard, or splitter cable. Sometimes USB fails; but PS/2 ALWAYS works.
