Check the memory module. It is possible that the memory module will not be generated for a long time, and the slot contact is poor, so plug and unplug the memory module again after unplugging it, and then turn it on and try again.

Check the motherboard battery. First, check whether the battery on the motherboard of the computer is still charged. If there is no electricity, then you need to replace the battery.

Check the graphics card. The nature of the graphics card is the same as that of the memory module, and it may rust if not used for a long time, so after removing the graphics card and the card, gently wipe off the gold finger with an eraser, and then reinstall it.

Clean up the dust. After opening the main chassis, clean up the dust.

A hair dryer can be used, but be careful to use cool breeze water.

Check the power supply. Many times, the machine can't be turned on, most of which is caused by the power supply being loose after not using it for a long time, so it is very important to check the power supply other than the computer host with hail.

Reasons and solutions why the computer can't be turned on for a long time:

1. Check the power supply.

Computers generally don't break down for no reason, even if they don't work for a long time. The system should not be broken, so when you encounter the problem of not being able to turn on, you must first check whether the external power supply can provide power. I've once encountered that the field attack macro is the power supply, and I don't know who unplugged it.

2. Check the display.

Sometimes the display is powered by an external power supply, so in addition to checking the power supply on the host, you should also check whether the power supply of the display is plugged in, and then turn on the display directly on the power supply to see if there is power.

3. Check the single situation of the host.

After confirming that the power supply of the host and the power supply of the monitor have been plugged in, press the power button of the host to see if the host has a light on. If there is no light in the book, see if the host makes a sound.

4. Check the power supply of the host.

If there is no sound after the host is turned on, then you have to check the power supply of the host, then the simple way is to disassemble the chassis, and then power on again to see if the power supply fan is rotating and whether the power supply is good. If it doesn't light up here, then you can basically tell that it is a problem with the power supply of the host.

5. The host is bright, but the display has only one bright spot.

Sometimes we will find that after the computer starts, only one cursor bright spot on the display screen is flashing, at this time the system should not be able to get up, then you can turn on the computer and press F8 to enter the safe mode, try to restore the factory settings.

6. The system can't get up.

If you can't turn on the machine, it's because the operating system can't get up, then the method is relatively simple, and you can directly solve it by reinstalling the system through the Zen Pai U disk.
