My aunt has recently switched and bought a new iMac G5 1.8 17". She keeps calling me to tell me that her mouse/keyboard turns off randomly when she is working on the comp. I went over and can't figure why it does it. It will come back on if I plug the keyboard into another usb port after a few seconds. It will do this on any usb port it seems. This is getting VERY frustrating b/c I have to hear the bi**hing. Any help? BTW: She has stock wired keyboard/mouse using the standard mouse plugs to keyboard, keyboard plugs to imac setup.
