If you're hearing beep codes after you turn your computer on, it typically means that the system has encountered some kind of problem before it was able to display any kind of error information on the monitor.
Follow the steps below to determine what system problem the beep code is representing.
Difficulty: AverageTime Required: Anywhere from 10 minutes to a few hours depending on the cause of the beep code
Power on the computer or restart it if it's already on.
Listen very carefully to the beep codes that sound when the computer begins to boot.
Restart your computer if you need to hear the beeping again. You're not likely to make whatever problem you have worse by restarting a few times.
Write down, in whatever way makes sense to you, how the beeps sound.
Important: Pay close attention to the number of beeps, if the beeps are long or short and if the beeping repeats or not. There is a big difference between a "beep-beep-beep" beep code and a "beep-beep" beep code.
This is all important information that will help determine what issue the beep codes are representing.
