About Dell Beep Codes
There is a PC Speaker built in motherboard on most PCs. Hence, even if the display can’t provide visual error description due to the faulty graphics card or the RAM that is not installed correctly, the computer buzzer that only relies on ROM and CPU can still operate normally and report the error that occurs during the boot process.
It can represent a specific error code through the permutation and combination of “beep” sounds, and the meaning of the code is based on different BIOS manufacturers.
