On a compaq presario the mouse and keyboard that came with it, both ps2, only partially function some of the time. At first they both wouldn't boot. Then I unplugged the mouse and the keyboard would work. I then plugged the mouse back in, and they both would work, but the cursor moved sporadically when i tried to use the mouse, and then the system speaker would beep and both the mouse and keyboard would stop working. Would could be causing this problem? I don't understand why the system speaker beeps or why a problem with the mouse could affect the keyboad. Can anyone help?
