How to Find Reasons of Pc Motherboard Beeping?

If you only hear a beep when you switch on your computer without the PC starting normal operation, the reason is a hardware problem or even a defect. The exact location of the problem can be determined from the beep – it varies depending on the source of the error.

When your computer starts up, the basic functions of the hardware are checked to ensure that everything works. If there are problems with this start-up check, the computer emits an acoustic signal.

When you assemble or remodel a PC, nothing happens when you switch it on for the first time, apart from a series of beeps.

The tones then help with troubleshooting because they provide a simple scheme to help you find the problem.

Most modern mainboards emit several tones of the same length. A pause follows it, and the sequence of tones is repeated. Older boards often even reproduce entire sequences of tones, including long and short or low and high tones.

It is how you can determine the cause of the error from the sound

The beep codes are not uniform. You can find a good reference for older motherboards in the free BIOS compendium, which you can download as a PDF, help file, or HTML file.

As an example of typical codes, here is the meaning of the signals on the current Intel mainboards for the Core-i5 and Core-i7 processors, in which the mainboard chipset Intel P67 Express is used:

  • 2 x beeps: graphics card error
  • 3 x beeps: Problem with main memory
  • 8 x beeps: heat problem

Main memory:

RAM modules are not fully engaged: try pushing hard until it clicks or the mounting brackets swivel up.

Incorrect order in which the bases are assigned: Always use the same colored bases (blue/black) with module pairs. When using only one memory module, use a certain socket (usually the one with the lowest numbering) depending on the motherboard. Otherwise, refer to the instructions to see what the manufacturer prescribes in terms of the assignment.

Defective memory modules: If you have several memory modules, do not install all of them, but try them all out individually. If it only beeps with some RAM modules, these are defective.

Additional power supply not connected: Many high-performance graphics cards require extra power. For this purpose, they either have a power connection like the drives or a special 6-pin socket that the power supply unit must offer. If there is no additional power supply, most graphics cards go on strike. So look in the instructions or look for a power connection on the graphics board that needs to be occupied.

Bus too fast: Older graphics cards cannot process the full bus speed. Then you have either to use a different, slower socket or turn down the speed of the PCI Express bus in the BIOS, which not every BIOS can do.

Overheating:

If the temperature sensors in the motherboard or the processor deliver too high values, there is a kind of emergency shutdown. First, check that the CPU cooler is correctly installed with thermal paste and that all fans are running.
