Bios audio codes

Bios – “basic input output system” - is the first simple operating system responsible for managing computer resources and communication between software and devices. Bios code is permanently stored in nonvolatile memory, created for read only.

bios audio codes Right after your computer is started, bios carries out so-called test post in which bios checks the major PC components such as processor, chipset, motherboard controllers, memory, and many other devices. If the bios encounters a problem during this test, it stops booting the computer and starts making sounds ( “beeps” ) signalizing the user existing problem. The most common problem is the physical damage to equipment. In case of passing the test normally, short signal is heard.

1 long, 2 short - graphics card error
1 long 3 short - error indicating a problem with the graphics card or its lack
repetitive sound - error indicating a problem with RAM
alternating high and low sound – processor error was detected
alarm while the computer is working – limit for allowable temperature for the processor is being crossed
