Here are some common steps a POST performs each time your computer starts.

  1. Test the power supply to ensure that it is turned on and that it releases its reset signal.
  2. CPU must exit the reset status mode and thereafter be able to execute instructions.
  3. BIOS checksum must be valid, meaning that it must be readable.
  4. CMOS checksum must be valid, meaning that it must be readable.
  5. CPU must be able to read all forms of memory such as the memory controller, memory bus, and memory module.
  6. The first 64KB of memory must be operational and have the capability to be read and written to and from, and capable of containing the POST code.
  7. I/O bus / controller must be accessible.
  8. I/O bus must be able to write / read from the video subsystem and be able to read all video RAM.
  9. If the Video or other parts of these steps encounters a problem then the system will emit a series of beeps that could let you know what the problem is.
I would disconnect all your devices from your motherboard except for the memory and the video and see if you can power up with the post messages on the screen. Make sure that your memory and your video card are seated securely. If you have 2 memory chips and 1 could be bad, you could remove 1 of them and try your power up again. The reason that we remove the other hardware from your system, is because they could be causing a conflict on the Motherboard.

My cpu is making 1long beep and 3 short beep sounds and not restarting.


This POST beep code usually means a RAM problem.
Try reseating your RAM module/s and reboot your computer.
Try the BIOS setting and check the RAM size, does it match the total installed RAM.
If you suspect the RAM is faulty, remove the RAM module/s and take it to your friendly computer repair shop and get them to test the RAM for you.

I have A desktop motherboard model asrock m266a,when i start it it will have 3 long beeps and stops for a while and another 3 long beeps


Hi.

3 long beeps means there's a problem detected with the keyboard. Remove the keyboard and turn the computer on and see if it boots up. Also a good idea is to make sure the system memory is seated properly in the slots.





Regards.

hi Robin.
if your computer is making a beeping sound when it starts. No, you're not crazy, your computer really is beeping, and the sound may be coming from inside your computer, not your speakers.
These beeps are called beep codes and are used by the BIOS (the software that runs your computer hardware) during the POST (an initial test to make sure your computer is OK to start) to report certain initial system errors. If you're hearing beep codes after you turn your computer on, it typically means that the motherboard has encountered some kind of problem before it was able to send any kind of error information to the monitor. The beeping, then, is a way to communicate a problem to you when the computer can't show a proper error on the screen.
Follow the steps below to determine what computer problem the beep code is representing. Once you know what's wrong, you can work to fix the issue.

How to Troubleshoot Beep Codes

Figuring out why your computer is making beeping sounds should only take 10 to 15 minutes. Solving that problem that you identify is another task entirely and could take a few minutes to hours, depending on what the problem ends up being.
  1. Power on the computer, or restart it if it's already on.
  2. 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.
  1. 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 (or all the same length), 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.

    I know this might all seem a little crazy but this is important information that will help determine what issue the beep codes are representing. If you get this wrong, you'll be trying to solve a problem your computer doesn't have and ignoring the real one.
  1. Next you'll need to figure out what company manufactured the BIOS chip that's on your computer motherboard. Unfortunately, the computer industry never agreed on a uniform way to communicate with beeps, so it's important to get this right.

    The easiest way to figure this is out is by installing one of these free system information tools, which should tell you if your BIOS is made by AMI, Award, Phoenix, or another company. If that doesn't work, you could open your computer and take a peek at the actual BIOS chip on your computer motherboard, which should have the company name printed on or next to it.

    Important: Your computer maker is not the same as the BIOS maker and your motherboard maker is not necessarily the same as the BIOS maker, so don't assume you already know the right answer to this question.
  2. 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 in those articles, 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.
  3. Try to turn off beep sound in the BIOS

More Help with Beep Codes

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.

Same problem


I would try to replace the PSU and see if that makes your computer boot. Do like a guess and check. If its not the PSU, maybe try a new motherboard. Does the computer not boot, or does it beep when turned on? I hope this helps solve your problem
