The problem started a few days ago when I plugged my mini ipod into the front USB port. I plugged the cable, already connected to the ipod, into the port, and my computer immediately crashed. I removed the plug from the port, pressed the power button, and the computer turned on again with no noticeable problem.
A few days later I plugged a USB cable into the front port again and the same thing happened; the computer immediately shut down on its own. When I tried to turn it on again, though, this time it just stopped a few seconds into start up and just persisted with the constant tone.
I already tried calling the support line, but they couldn't help. Is the problem obvious? Is it something like a broken fan or a burnt drive?
I would appreciate any sort of help or suggestion. Thanks.
