Finding out what your computer beep codes, PC beep codes mean or POST beep codes are is a simple step in figuring out whatever problem is there that is preventing your computer from starting up. If your PC speaker isn't connected, visit computer tower cases and I'll show you how to get your PC speaker connected to the motherboard so you can hear the beep codes.
There are short beeps and long beeps. Simply count the beeps, either short or long and write down how many you counted. 1 short beep for example is the sound of a good POST. All is well and the computer will start up. For the purpose of this page, we're going to use the standard IBM beep codes. Almost all the computers on the market have adopted these and continue to use them.
If you know what type of BIOS you have and you don't find your
beep code listed below, you can simply search for the type of BIOS you
have followed by beep codes to give you a complete list for your BIOS.
Your motherboard documentation should also tell you what type
of BIOS is installed in your computer.
TIP! I just use the list I have below for computer beep codes, at the time of this writing, I've never needed the complete list by BIOS type.
Sometimes you will get a short beep signifying the computer has booted up properly, but you don't have any video. This usually happens when a video card is finished, but can also happen if you have a weak power supply or the video card needs cleaning and continuously shuts itself of on boot.
