This article explains how to figure out why your PC is beeping by noting the beep pattern, determining your computer’s BIOS maker, and consulting the matching online guide. If you’re hearing beep codes after you turn your computer on—and then it doesn’t start—it means the motherboard encountered some kind of problem before it was able to send any error information to the monitor.

Follow these steps below to determine what problem the beep code is representing. Once you know what’s wrong, you can work to fix the issue. 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 probably not going 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.

Pay close attention to the number of beeps, if the beeps are long or short or all the same length , and if the beeping repeats or not.

There’s a big difference between a “beep-beep-beep” and a “beep-beep. Yes, this might all seem a little crazy, but this is important information that will help determine what issue the beep codes are representing.

Your computer maker isn’t the same as the BIOS maker and your motherboard maker isn’t necessarily the same as the BIOS maker, so don’t assume you already know the right answer to this question.

Now that you know the BIOS manufacturer, choose the troubleshooting guide below based on that information:. Using the beep code information specific to those BIOS makers, you’ll be able to figure out exactly what’s wrong that’s causing the beeping, be it a RAM issue, a video card problem, or some other hardware problem. Some computers, even though they may have BIOS firmware made by a particular company, like AMI or Award, further customize their beep-to-problem language, making this process a little frustrating.

If you think this might be the case, or just worried it could be, almost every computer maker publishes their beep code list in their user guides, which you can probably find online.
