Damage to the computer's "tool" - dust

What can damage the computer host? Is it a system virus or a Trojan virus? In fact, there is another thing we ignore, that is, dust, so we usually pay attention to computer software anti-virus while keeping the computer host clean.

One. Check the power and restart button is a physical failure, the most common is to press and not to get up, any of the two buttons can cause this problem, can cause the computer can not boot properly. The solution can only be repaired or replaced, because the chassis is integrated inside the chassis, making it difficult for ordinary users to repair.

Second, open the chassis, unplug the motherboard BIOS power, wait a moment, then press again to see if the computer can run normally.

Third, unplug the motherboard and the chassis, and touch the motherboard power control pin with a screwdriver (because there are many pins, please confirm the power control pin, please refer to the motherboard manual, do not bump, will burn the motherboard ), if booting normally, it proves to be a problem with the chassis boot and reset button. The solution is the same as above.

4. Unplug all the data and power cables between the power supply and the motherboard, optical drive, hard disk, floppy drive, etc., and pull all the devices on the motherboard back, such as the monitor, network cable, mouse, and keyboard. Next, blow dry the dust on the motherboard power socket and the power plug, then plug it in again and turn it on. If it can be turned on, plug the device one by one to confirm the source of the fault. After confirming, the faulty accessory can be updated to solve the problem.

After all the above four steps have been tried, it is still impossible to determine the source of the fault. In the case of the current equipment, it is impossible to determine the source of the fault. Only the host computer can be sent to the repair station. The estimated fault is: the power supply or motherboard burned.

Sometimes the computer failure is not caused by a system error, it may be a physical failure, but the above steps are used to remove the obstacles, and the cleaning work of the computer should also be paid attention to, so that the computer will not be subjected to harm.
