Computer now has become a daily necessities of life, then how much do you know about computers? The following small series for you to organize some common computer hardware knowledge, quickly to learn!
Computer hardware, including all the physical parts of a computer, to differentiate between the data it contains or executes and the software that provides instructions for the hardware to complete the task. Computer hardware mainly includes: chassis, motherboard, bus, power, hard disk, storage controller, interface card, portable storage device, built-in memory, input equipment, output equipment, CPU fan, buzzer and so on.
Boot motherboard beep Reason
1 short: The system starts normally. Indicates that there are no problems with the machine.
2 Short: General error, please go to CMOS setup and reset the incorrect option.
1 long 1 short: Memory or motherboard error. Try another memory, if not, have to replace the motherboard.
1 long 2 short: monitor or display card error.
1 Long 3 short: Keyboard controller error. Check the motherboard.
1 Long 9 short: motherboard Flash RAM or EPROM error, bios damage. Try the flash RAM for another piece.
Keep ringing (long sound): the memory strips are not plugged in or damaged. Reseat the memory bar or replace the memory.
Keep the alarm: power supply, monitor does not connect with the display card. Check all the plugs.
Repeat short sound alarm: There is a problem with the power supply.
No alarm no display: There is a problem with the power supply.
1 Short: Memory refresh failed. Replace the memory strips.
2 short: Memory ECC more error. The option to disabled memory about ECC checksums in CMOS setup can be resolved, but the most fundamental solution is to replace a single memory.
3 Short: System basic memory check failed. Swap memory.
4 Short: System clock error.
5 Short: CPU error.
6 Short: Keyboard controller error.
7 short: System Real mode error, can not switch to protection mode.
8 Short: Memory error displayed. There is a problem with memory, try replacing the video card.
9 Short: BIOS chip test and error.
1 Long 3 short: Memory error. Memory is damaged and can be replaced.
1 Long 8 short: Display test error. The monitor data cable is not plugged in or the display card is not in a good cell.
1 Short: System boot normal
1 short 1 Short 1 short: System initialization failed
1 short 1 Short 2 short: motherboard error
