It may be due to hardware reasons that cause aging and damage to the motherboard, resulting in motherboard failure; or random hot-swapping of hardware or indiscriminate use of metal objects to touch various connectors may cause motherboard failure. ; It may also be caused by dust and static electricity.

The following is a detailed introduction:

1. It may be due to hardware reasons that the motherboard is aging and damaged, resulting in motherboard failure;

Human reasons: when using the computer , hot-swapping hardware at will or touching various connectors with metal objects will cause motherboard failure;

Causes of dust and static electricity: Dust or static electricity may lead to poor motherboard contact, short circuit or burnt chips on the motherboard. Motherboard failure. ;

Causes of poor contact: Due to corrosion, oxidation, weakened elasticity, desoldering, breakage of pins and other reasons, various chips, sockets, and interfaces in the motherboard are in poor contact, resulting in motherboard failure.

2. First check whether the external wiring of the computer is connected properly, and re-plug each connection to see if the fault is eliminated.

3. If the fault persists, then open the main case and check to see if there are any excess metal objects in the case or a short circuit caused by the deformation of the motherboard. Smell whether there is a burning smell in the case and whether there are any burnt parts on the motherboard. Whether the capacitors around the chip and CPU are damaged, etc.

4. If not, then clean the dust on the motherboard and check whether the computer is normal.

5. If the fault persists, unplug the Reset line and other switches and indicator light connections on the motherboard, and then use a screwdriver to short-circuit the switch to see if it can be turned on.

6. If the computer cannot be turned on, then use the minimum system method to unplug the data cables of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. If a startup screen appears on the computer monitor, it means that the problem lies in these areas. devices. Then connect more than one device to the computer one by one. When a certain device is connected, the fault reappears, indicating that the fault is caused by this device. Finally, focus on checking this device.

7. If the fault persists, the fault may be caused by memory, graphics card, CPU, motherboard and other equipment. Then use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal. If there is any damaged equipment, replace the damaged equipment.
