When you turn on the computer beeps

The essence of the problem: When the computer turns on, it immediately starts squeaking.

Solution:

1. You need to know the BIOS manufacturer of your motherboard. The easiest option is to find the name of the BIOS manufacturer in the instructions for the motherboard. If the instruction you didn’t save, open the system unit, look at the motherboard model, go online with the computer of friends, relatives, neighbors and look for the BIOS manufacturer

2. If you still decide to open the system unit yourself, then all the actions inside must be performed with the power turned off, first removing the electrostatic charge from yourself (before touching parts inside the computer, touch the metal chassis of the case). Even after removing the electrostatic charge, try not to touch the terminals of the microcircuits.

3. If you doubt your knowledge and ability to fix the malfunction yourself, contact a specialist.

The following are decryptions of the BIOS signals of the two most popular manufacturers – Award BIOS and AMI BIOS:

If there are no signals at all, you need to check the power supply, it may be malfunctioning or not connected to the motherboard. You can try to clean it of dust, check the reliability of the power connector on the motherboard. If the above tips did not help, the power supply must be replaced or returned for repair.

Award BIOS:
– solid continuous signal – power supply is defective;
– 1 short signal – no errors were detected, the PC is working;
– 1 short periodically repeating signal – problems with the power supply;
– 1 long periodically repeating signal – a RAM malfunction (we try to remove the RAM module from the slot and insert it again, if it doesn’t help, you need to replace the module);
– 2 short signals – minor errors were detected (we check the reliability of fastening loops and cables in the connectors of the motherboard, set the BIOS default values ​​(item Load BIOS Defaults);
– 3 long – the keyboard controller is faulty (we check the integrity of the keyboard cable and the quality of the connections, we check the keyboard on a known-good computer, if it does not help, we need to repair or replace the motherboard);
– 1 long, 1 short – RAM malfunction;
– 1 long, 2 short signals – malfunction of the video card (try to pull out the video card and reinsert it, check the integrity and quality of the connection of the monitor cable, if it does not help, you need to replace the video card);
– 1 long, 3 short – keyboard malfunction;
– 1 long, 9 short – an error occurred while reading data from the BIOS microcircuit (a microcircuit flashing is required; if it does not help, a microcircuit replacement is necessary.

AMI BIOS:
– 1 short signal – no errors were detected, the computer is operational;
– 2 short signals – RAM malfunction (try to remove the RAM module from the slot and insert it again, if it doesn’t help, you need to replace the module);
– 3 short – error of the first 64 Kbytes of main memory;
– 4 short ones – malfunction of the system timer (restart the computer, if it does not help, you need to repair or replace the motherboard);
– 5 short signals – malfunction of the central processor (restart the computer, if it does not help, it is necessary to repair or replace the central processor);
– 6 short – keyboard controller malfunction (we check the integrity of the keyboard cable and the quality of connections, we check the keyboard on a known-good computer, if it does not help, we need to repair or replace the motherboard);
– 7 short – motherboard malfunction (restart the computer, if it does not help – you need to repair or replace the motherboard);
– 8 short ones – a malfunction of the RAM of the video card (restart the computer, if it does not help, you need to repair or replace the video card);
– 9 short ones – an error occurred while checking the checksum of the BIOS microcircuit (a microcircuit flashing is required; if it does not help, a microcircuit replacement is necessary.
– 10 short – it is impossible to write to the CMOS memory. We try to reset the contents of the memory. To do this, turn off the computer, remove the network cable from the outlet. We look for the switch next to the CMOS memory battery and set it to Clear CMOS. Click (!!! when the network cable is disconnected !!!) – the power button on the computer. Set the switch to its original position. If there is no switch on your motherboard, you need to remove the battery for 30 minutes or more. Set the default BIOS settings (Load BIOS Defaults). If it does not help, a BIOS chip needs to be replaced;
– 11 short – RAM malfunction;
– 1 long, 2 short signals – malfunction of the video card (try to pull out the video card and reinsert it, check the integrity and quality of the connection of the monitor cable, if it does not help, you need to replace the video card);
– 1 long, 3 short – video card malfunction;
– 1 long, 8 short – video card malfunction.
