No power to all USB ports, tried the cuda reset a couple of times, can't do pram reset as the keyboard is USB...... After this started to happen I was able to get the Mac to start up once, but it froze about 15 seconds after startup completed. I have Applecare and will call them today when I get home from work, but was hoping that I could fix it myself.... Still it seems odd that this would suddenly happen. I checked the video card everything. the USB ports in the monitor are just a hub fed by one of the rear ports on my Mac, I have a 22 inch NEC CRT... Any suggestions would be helpful, at least I have Applecare to turn to at the end of the day...
