Some children's shoes when the computer fails, the computer will emit a "drop" sound, for the novice, such a drop of sound is no different.In fact, this is the alarm sound of the self-checking during the computer's boot process. It tells the user where the computer's fault occurred through different alarm sounds so that the user can prescribe the right medicine for maintenance.

First of all, I popularize what is the post test

Power-on self-check is the process of checking the hardware, such as the hard disk, memory, graphics card, CPU, etc., during the boot process of the computer. If the hardware device fails, it will give a warning through “drip” and sometimes it will not start up. . To understand the meaning of BIOS alarms, you need to understand what kind of BIOS you have.The following are the fault contents of the BIOS self-test alarm sounds:

Analysis of the Corresponding Faults of Computer's Power-on Self Test Sound

Award BIOS

1 Short System Normal Startup 2 Short Regular Error, Please Enter CMOS SETUP Reset Incorrect Option 1 Long 1 Short Memory or Motherboard Error 1 Long 2 Short Display Error (Monitor or Display Card) 1 Long 3 Short Keyboard Controller Error 1 Long 9 Short board FlashRAM or EPROM error (BIOS corruption) Continuous ringing (long tone) Unstable or damaged memory socket. Power is constantly on the monitor. The monitor is not connected to the video card. Repetitive short ring Power problem No sound No display Power problem

AMI BIOS

1 Short memory refresh failed 2 Short memory ECC check error 3 Short system memory base (1st 64K) Check failed 4 Short system clock error 5 Short CPU (central processing unit) error 6 Short keyboard controller error 7 Short system real mode Error, cannot switch to protected mode 8 short display memory error (display memory may be broken) 9 short ROM BIOS checksum error 1 long 3 short memory error (memory damaged, replace) 1 long 8 short display test error (monitor data cable Loose or stuck in the display card

Phoenix BIOS

1 Short system normal startup 3 Short system power-on self-test initialization (POST) failed 1 short 1 short 2 short motherboard error (motherboard damaged, replace) 1 short 1 short 3 short main board battery is dead or CMOS is damaged 1 short 1 short 4 Short ROM BIOS check error 1 short 2 short 1 short system real time clock problem 1 short 2 short 2 short DMA channel initialization failed 1 short 2 short 3 short DMA channel page register error 1 short 3 short 1 short memory channel refresh error (problem The range is all memory) 1 short 3 short 2 short basic memory error (memory corrupt or RAS setup error) 1 short 3 short 3 short basic memory error (most likely memory corruption on DIMM0 slot) 1 short 4 short 1 short basic Memory address error 1 short 4 short 2 short system basic memory (1st 64K) with parity error 1 short 4 short 3 short EISA bus sequencer error 1 short 4 short 4 short EISA NMI port error 2 short 1 short 1 short system base memory (1st 64K) check failed 3 short 1 short 1 short 1st DMA controller or register error 3 short 1 short 2 short 2nd DMA controller or register error 3 short 1 short 3 short main Interrupt Handling Register Error 3 Short 1 Short 4 Short Sub-Interrupt Handling Register Error 3 Short 2 Short 4 Short Keyboard Clock Asked Problem, reset to Not Installed in CMOS to skip POST 3 short 3 short 4 short display card RAM error or no RAM, not a fatal error 3 short 4 short 2 short display data cable is loose or display card is not stable or Display Card Corrupt 3 Short 4 Short 3 Short Not Found Display Card ROM BIOS 4 Short 2 Short 1 Short System Real Time Clock Error 4 Short 2 Short 2 Short System Boot Error, Improper CMOS Setup or BIOS Corrupt 4 Short 2 Short 3 Short Keyboard Controls There is something wrong with the Gate A20 switch in the device (8042) and the BIOS cannot switch to protected mode. 4 Short 2 Short 4 Short Protection Mode Interrupt Error 4 Short 3 Short 1 Short Memory Error (Memory Corrupted or RAS Set Error) 4 Short 3 Short 3 Short System Second Clock Error 4 Short 3 Short 4 Short Real Time Clock Error 4 Short 4 Short 1 Short serial port (COM port, mouse port) Fault 4 Short 4 Short 2 Short Parallel port (LPT port, print port) error

Everyone can register their seats according to their own alarm conditions and apply drugs.
