A ps2 keyboard or mouse will have a round plug as opposed to the flat one that a usb has. Usually the computer will have two ports dedicated to that type of connector. Often they are color coded purple and green. At this point I don't think a wireless is your best choice. As mentioned if you don't have a ps2 connector on your keyboard, you can get an adapter that allows you to plug in a usb connector into a ps2 port. When all else fails, sometimes its best to take it to a local computer repair shop. They would have some of the "tools" necessary to help you out.
