I have received 5 pop-ups stating: USB Over Current Notice A USB device is currently drawing too much power. The hub it is attached to will be deactivated. Every time I click "OK" the window will disappear and then reappear instantly. The notices appeared when I woke my iMac G5 from sleep. I have never gotten this notice before so I unplugged my printer, iPod shuffle, and an empty USB extension cord but the notices will not go away. Also running at the time were Firefox and Microsoft Word. The bars on my Activity Monitor gauge are all full and my fans are running pretty loud. Also I am running version 10.3.9 on a non-isight iMac G5. If anyone could please help me out as to what is going on with my Mac, that would be great! Thanks!
