Can some one help me? My sister borrowed my iMac G5 to load some photos from her digital camera. She called me up and the iMac was frozen. (never happened before) Ok the screen read "Usb device is drawing too much power, component will be disconnected" Ok, I did a restart and the iMac took a long time to boot up (again unusual) This time my mouse and keyboard lights were blinking on and off and the iMac is still frozen. I restarted again and then the searching for mouse and keyboad utility pops up on the screen, even though both are plugged in. I unplugged them and restarted, then plugged them in again at the start of the utility. No luck. I brought in another pair of keyboard and mouse set and tried again. No luck. By this time I've restarted at least six times. Now my imac starts and freezes and the utility screen. I have no idea what to do, does something need to be reset or something? can some one help me?
