How to repair the computer if the alarm switch of the computer host does not work?
Maybe the memory was oxidized. Turn off the power of the computer, face the host and open the cover on the left side of the computer. There are two white buttons next to the memory. When you break up, your memory will come back. Find an eraser with gold on it. Wipe both sides. However, when plugging back into the motherboard, remember that the sizes of the two sides of the memory are different, and all of them must be buckled before booting. If this method doesn't work, then it may be to change the memory or the motherboard.
What if the computer host calls the police?
1. If you hear two short motherboard alarms, it may be that there is something wrong with the memory parity. At this time, we can enter CMOS to set and close the options of parity items in the memory. Of course, if it is normal, it is suggested to turn on parity, which is helpful to the stability of the computer system.
2. If you hear three brief motherboard alarms, it means that the basic memory check of the system failed. It is best to replace the memory at this time.
3. If you hear four brief motherboard alarms, it means there is something wrong with the clock of the computer system. At this time, the motherboard needs to be repaired, and the motherboard can be replaced if necessary.
4. If you hear five short motherboard alarms, it means that there is something wrong with the CPU of the computer, which may be your own problem, the CPU socket or other problems. If there is nothing wrong with the CPU, then the problem will definitely appear on the motherboard.
5. If you hear six short motherboard alarms, there is something wrong with the keyboard controller of the computer. Maybe the keyboard is not plugged in properly, or maybe there is something wrong with the keyboard itself. You can try a different keyboard.
The alarm of the computer mainframe drips.
The computer gives a drip alarm.
1 short: the system starts normally. This is what we hear every day, which also shows that there is nothing wrong with the machine.
2 Short: General error, please enter CMOS.
Set and reset incorrect options. 1long1short: Error in RAM or motherboard. Try to change your memory. If it still doesn't work, we will change the motherboard.
The computer mainframe drips water because the oxide layer is formed on the surface of the gold finger of the memory or discrete graphics card, resulting in poor contact between the memory and the memory slot, and poor contact between the graphics card and the graphics card slot, resulting in black screen and dripping sound.
