When several motherboard BIOS alarm sounds, when we repair the computer, we will often encounter boot, BIOS's error prompt, if we are familiar with these sounds, we are very convenient when we exclude computer failure, can be in shortest Solve problems during time. 1, "嘀 ..." continuous short tone is generally problematic. There is a problem with the power supply of the host. However, when the power output voltage is low, the host does not alarm, but the hard disk is lost, the optical drive is poor, and the case where it is often crafted. When these conditions occurs, it is best to check the output of each voltage, whether it is low, when 5V and 12V are less than 10%, the above problems will occur. Because the power supply has voltage output, it is often mistaken to have problems or hard disk problems for the motherboard, while a waste of time. The reason why the output voltage is low is that the filter capacitance of the output portion is lost or leakage. When the DC component is lowered, the high-frequency communication ingredient in the power supply increases, which will interfere with the normal operation of the motherboard, causing the system unstable and easy to appear. Cancer or blue screen phenomenon. But this situation is on the main board of Intel and Gigabyte, if the system appears "嘀 ..." continuous short sound, is not a power failure, but a memory fault alarm, this needs attention. 2. "" ambulance, accompanied by booting long, it is the system alarm of CPU overheating, mostly because dust removal is dust removal, cleaning the CPU radiator or because of the replacement CPU fan, because the installation is not in place, the CPU radiator is inaccurate, there is a certain space or therethrough, causing the calorific for the CPU to be removed normally, and the boot CPU is as high as 80-90 ° C. If it is the CPU below PIII, because the temperature test of the CPU is collected by a temperature probe near the CPU, the temperature value of the display has a certain error with the actual temperature value of the CPU, about 10-20 ° C. The PIV CPU temperature sensor is integrated inside the CPU, and the CPU temperature displayed in the system is relatively accurate. Generally, the host is turned on, the system prompts the CPU temperature of about 50 ° C, which is normal. 3. "... ..." continuously there is a spacing of long tones. This is the sound of memory alarms, which is generally internal memory, and the memory finger and memory slot are poor contact. The gold finger oxidation of memory is oxidized, and a certain chip of memory has a failure. 4. "嘀 ..., 嘀嘀", a long two short continuous twezed this is a graphics card alarm, usually the graphics card is loose, the graphics card is damaged, or the motherboard's graphics power supply section is faulty. 5. "Dudu" has no movement after the two essays, I will hear the sound of "gure" reading software. If an image display prompts that the system will start from the floppy drive, the floppy is read. If there is no floppy disk in the floppy drive, the system will prompt the system that cannot be started, the system hangs. 6. When you press "Caps Lock" and "Num Lock" and "Scroll Lock", press "Scroll Lock", the host's PC speaker has a "" similar button tone. For example, the PV40ML of the three emperors is a prompt function of the motherboard, prompting the user to change the input status of the keyboard, not a fault. But because some people don't understand the fake, it is considered to be a problem with the motherboard. 7. Short "嘀" is in general, this is a prompt that the system self-test passes, the system is started normally. However, some motherboards passed the self-test, there is no such tone, and there is no sound. Also note that some motherboard self-tests may be longer, will wait for five or six seconds to hear the "", need a little patience.
