If your Dell computer won't load, you might hear one or more beep sounds. The number of beeps can tell you what the problem is. This guide will help you understand what the beeps mean.

Fixing the problem


This list tells you what each number of beeps means:

  • 1 beep: Possible motherboard failure or BIOS corruption.
  • 2 beeps: Memory not detected.
