Question about Computers & Internet
The beeps you are hearing are the "POST codes" POST stands for "Power On Self Test" The series of beeps provides a starting point for troubleshooting when a computer is unable to boot up properly.
POST codes are not standardized. Each manufacturer has their own set of POST codes, so you'll need to know which brand computer you have - or in the case of a computer that was built for you (as opposed to those purchased at large chain stores and made by the likes of HP, Dell, IBM, Gateway, etc. - you'll need to determine the manufacturer and model of the motherboard. The motherboard (MoBo) information is usually printed on the board itself - in a relatively easy to read location.
Once you have this information, you'll have to contact the manufacturer (either customer support telephone number or a support website) and search for POST codes definitions. Many POST codes consist of one or more groups of two or three beeps ie: 2-1 or 2-1-3 as opposed to simply 3 or 6 beeps in the example. There may be more than just one beep code group - so listen up and pay close attention to the beeps. If you can't find the POST definitions - give me the computer / MoBo info and I'll see if I can find it for you.
I hope this helps!

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.
What steps you take to solve a particular beep code will differ depending on the BIOS manufacturer.
