Many people know that when you start your computer, you first boot the BIOS, which immediately scans and checks all the devices on the condition and ability to function normally.BIOS beep codes when Windows is due to the fact that the system detected some mistake.
Of course, all of them almost impossible to remember, so you always need to have the instructions before your eyes.Or, for example, print this article and use it in the future.
worth noting that the BIOS from different manufacturers differ, and consequently also the sound signals.
For reference, I would say , how you can identify a BIOS, so you know, just in case something happens, and were able to correctly identify the initialization error.Title seen PC startup, or by means of what some programs, for example, Everest (Aida).
start with the old men.I do not think it necessary to describe all sorts of options signals, and it is worth mentioning only the most basic and common.
signals BIOS of IBM:
1 short: POST completed successfully.That is, the errors found.
Blank and 1 signal: video system is faulty, in connection with which the information is not displayed.
2 short: monitor is not connected.
1 long and 1 short then: revealed problems with the motherboard.
one long and then two short: card has some problems (Mono / CGA)
If 1 long and then 3 short: card has some problem (EGA / VGA)
Shortsignal, which is either a recurring or continuous: any faults or defects in the motherboard or power supply.
If the signal is absent , it means that you are not running the speaker, motherboard or power supply.
signals AMI BIOS :
1 short: POST completed successfully.That is, the errors found.
1 long and 1 short then: found some problems with the power supply.
1 long and then short 4: card is not detected.
2 short: enabled printer or scanner.
3 long beeps: problems RAM.Try reinstalling it, or replace line.
4 short: system timer has failed.
5 short: found some problems with the processor.
7 short: at the mat.board identified problems.
8 short: video card memory fails.
one long and then two short: card has some problems (Mono / CGA)
If 1 long and then 3 short: card has some problem (EGA / VGA)
1 long and then short 8: not monitor or video card is defective.
Blank screen and the lack of any signal: processor has failed or poor contact at his feet.
signal is continuous: faulty power supply or the computer is overheating
signals BIOS of Award:
1 short: POST completed successfully.Any defects found.
2 short beeps: were found only minor interference.You will need to check the contacts and various attachment loops, hard drives, optical drives and the like.
3 long: error caused the controller to work with the keyboard.
1 short and 1 long followed: error reading or writing information from RAM.
1, and then a long 2 short: detected errors graphics.
1 long and 3 short then: error reading or writing information from the video memory.
1 long and 3 short then: error reading or writing data from the ROM.
short signal which is periodically repeated: revealed some defects in the power supply.
Long signal that periodically repeats: Problems with RAM.
repeating sound, then high, then low frequencies: problems with the processor.
continuous signal: faults in the power supply.
And lastly ... If you have some other version of the BIOS, or you want to know all sounds BIOS, that go to the manufacturer's website and see the instructions.If you do not find detailed instructions on such sites, try looking for more information on the links that are provided in the program Everest.
