Each time you boot, the system unit of the computer emits a squeak, which indicates the health of the operating system and the computer as a whole. However, sometimes there are other sound signals, which not everyone can decipher. These squeaks are the result of testing the hardware of your computer. At each boot, the machine tests all connected components, and the system unit notifies the result of the test with a squeak.
If you hear one short squeak, then don't worry. This means that everything is fine and the test will be successful. Sometimes the structure of the system unit is such that when it boots successfully, it does not make a sound at all. Just keep working.
If you hear one continuous long squeak, then you should be alert. Most likely, there are problems with the power supply. In most cases, the only solution to this problem is to replace with a new device.
Two short squeaks indicate minor malfunctions in the BIOS component settings. To fix this, you need to go to its menu and set the optimal parameters there. If you are not sure which options to select, set the default settings. To do this, you need to press the F5 button. Sometimes the menu already highlighted settings items that conflict with the system.
Three long beeps indicate no keypad. Check if this peripheral is connected. If the keyboard is firmly stuck in the slot, but the squeak does not disappear, most likely you need to change the device itself. Short signals tell us about an error in RAM. It is necessary to check if there are memory blocks on the motherboard. You can also try to take out all the strips, carefully clean them from the accumulated dust and, alternately inserting them back into the connectors, try to start the computer. If the case of the system unit emits the same three squeaks on one of the slats, it means that you need to change it.
One short and one long squeak is a signal that the RAM is not working properly. The verification procedure is similar to the previous one. Perhaps the problem lies in the fact that some of the planks are incompatible with each other.
The presence of one long and three short signals indicates that there are problems with the video adapter. To do this, you need to check the performance of your video card using a known working one. You can also try pulling out the card, dusting it, and then reinserting it.
