When I have my keyboard plugged in to the ps2 port it will "go crazy", copying and pasting recently typed text over and over again until it beeps and stops working. A friend suggested using a usb adapter. This works better, but every so often (twice just typing this) the keyboard stops for a moment, all the lights flash and then it comes back. It does this on 2 different keyboards. I have no idea what to do. BTW, I can give system info if requested, I just didn't know what would be relevant. Thanks.
