My computer didn t turn on properly before, and after a few months, I wanted to turn on normally, bu

One. It is caused by the power supply being energized for a long time, receiving and occurring the start signal and crashing without the block, and the start signal can be sent normally.

Solution: Turn off the power of the socket or unplug the power cord of the middle and lower hosts, press the start button of the computer host, and then turn on the power of the host or plug in the power cord of the host.

Two. It may be that the gold finger is oxidized due to moisture.

Solution: Remove the memory and graphics card, erase the gold finger part with an eraser, and reinstall it.

Can't even turn on the power supply?

1) Reinstall the operating system first, don't install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

2) If it is caused by hardware problems, it is recommended to overhaul it.

It is likely that the wiring is damp, or static electricity has accumulated.

If the computer is not used for a long time and cannot enter the system after booting, it is mostly caused by moisture or poor contact, or the system files are lost, or it may be that a hardware is broken.

1. Put the computer host in a ventilated and backlit place, cool for an hour or two, and then connect it with the monitor, mouse, and keyboard, and test whether it can enter the system when it is turned on.

2. Restart your computer and press the F8 key until the Windows Advanced Options menu appears. Use the arrow keys to select "Last correct configuration", or "Safe Mode" to turn on the computer to see if it can enter the system. If you can use software such as 360 to clean and optimize your computer, repair the system, and restart your computer.

3. If you can't enter the system, shut down, open the chassis, remove dust, and plug all the connections tightly and firmly.

4. Check the motherboard battery, replace the battery, set the BIOS to the factory default, and set the hard disk as the first boot.

5. Start up and try again, it doesn't work, it's the system files are lost, reinstall the system.

6. The system cannot be installed, it is a hardware failure, and there is a condition to replace the suspected problematic hardware with a replacement method.

Desktop computers are the most likely to have problems if they are not used for long periods of time.

Current breakdown is the most common, due to long-term use of the computer case, the internal air humidity is relatively large, once the power is on, it is easy to break down the capacitance on the main plate.

I also don't want the landlord's computer hardware to have problems, but the computer is still often good, which is why the computer in the Internet café is used 24 hours a day, but it is not bad, if it is not used for a long time, you can clean up the dust before starting, unplug the memory, graphics card and other components, and brush it off with a clean brush.

According to the current situation, the biggest possibility is that the graphics card or memory is not in good contact, and if it doesn't work to try to plug and unplug again, it is estimated that the hardware is broken.
