If for some reason the computer does not start up, sometimes a strange BIOS sound is heard. There are several such signals, they depend on what kind of problem arose from the PC. We’ll understand their meaning now.
Bit of theory
So, in the event of a hardware error, the personal computer sends
internal speaker signals, they can be decrypted. First you need to determine which BIOS you are using. This is necessary because computers with different configurations have different signal coding. How to find out the BIOS model? At boot time, the first thing the user sees on the screen is the name of the element we need. If you simply do not have time to consider the inscription, go to “CMOS SETUP” using the DEL key (this command can be executed in different ways, depending on the configuration of the computer). Most often, the BIOS brand is written at the top. However, if your monitor does not want to display the image on the screen, you need to get inside the PC, after which there you can find the chip of this element on the installed motherboard. Next, we will analyze the decryption of signals for various BIOS configurations.
AWARD BIOS
If the BIOS signal that you hear is single and short, then everything in
completely in order and the operating system is currently loading. When one long and only short “exclamation” occurs, it means that a DRAM error has occurred and you need to check the memory. When
BIOS signals, 2 short, sound, it is a SMOS error. You must go into Setup, and then install everything again. You should also try replacing the battery. In addition, three short BIOS signals, preceded by one long, indicate a keyboard controller error. It is necessary to check whether this control is connected to the computer. When the BIOS signal is looped short, it means that you are faced with a power supply error. In turn, if it is looped long, the memory board is not installed correctly. Sometimes you can hear one long and two short sound symbols from the system, they occur if a video card error has occurred. You should check the quality of the connection of your video card to the slot, as well as the condition of the monitor. It may also not be connected to a working video card. The last thing the
system configuration can upset us with is a code of one long signal and nine short signals, thereby telling about a ROM error (BIOS).
AMI BIOS
Remember that at the start of a personal computer, at least one sound designation should sound. If there is no BIOS signal, the internal speaker is probably malfunctioning or malfunctioning or the motherboard is burned out. If you hear a single sound, that’s good, then everything works correctly. However, if the image does not appear on your monitor, then you need to check whether it is connected to the video card (and it, in turn, to your motherboard). So we figured out the task. Listen to your computer!
