How do I reinstall the system if my computer can t be opened, and what happens when my computer can

This "can't be opened" should mean that the machine is not lit, otherwise it is very convenient to reinstall the system.

If the machine is not lit, first observe whether the machine has an alarm sound, because the problem point can be judged according to the alarm sound.

Detect the memory module, because if the basic memory can't be detected, it is also a black screen.

There is also the power of the motherboard battery, and the machine cannot be started when the battery is low.

In short, light up the machine first, so that you can choose the equipment to install the system and execute the installation procedure.

The computer won't open, so you can only use a USB drive to reinstall the system. Install PE on the U disk and put it into the system, press the start hotkey to enter the PE when you boot it, and you can reinstall the system.

Buy a CD.,It's bootable.,There's a ghost system.。 Computer companies generally have it.

After booting up with a disc, it's easy to get the system up and down by following the prompts.

However, before installing the system, you must advance the PE system on the CD, enter the C drive to back up the useful information, otherwise the C disk files are gone.

I don't know what you mean when you say can't turn on.

If the computer is turned on, it will not light up.

That definitely can't be systematized.

If it can be opened, it just can't get into the system.

You can put the disc in it and set it to boot from the disc in Bois.

Then reinstall the system.

ISO itself is a compressed package, you can directly compress to other drive letters (except C disk), click install directly, the system will automatically restart, start the installer.

Possible reasons are:

1. There may be compatibility problems after reinstalling the system, such as changing the system from 32-bit to 64-bit, which may cause the software to be unusable, and you can only reinstall the compatible software;

2. When reinstalling the system, the C drive is formatted, the registry related items are deleted, and the things on the desktop are also deleted, which may lead to incorrect paths, or the folder where the software is located will also cause incorrect paths after being moved;

3. There is also a possibility that the software running needs specific program support, and there is no corresponding program or version in the new system, such as the support of directx 9 that many games need.
