"Why does my computer beep at me when I turn it on?"に関する回答A computer that is beeping when turned on indicates that an unrecoverable error occurred during the Power On Self Test, and that the display could also not be enabled to show an error message. The beeping is an indicator of what problem was encountered. Identify what the problem is with the manufacturer's beep code guide in order to find out what to do to fix the problem.
