Hello, 1. Motherboard problem, may need to be repaired;

2. If there is a problem with the motherboard settings, it is recommended to restore the BIOS to the factory default settings;

3. Turn off the computer for a few minutes and turn it on again, sometimes the problem can be solved by itself.

Step 1: Unplug all unnecessary external equipment, leave only the mouse keyboard and monitor and power cable, after turning on to see if it can be used normally, if it can, it means that other devices cause the mouse to be unusable, one by one plug in to boot detection, see what is caused by the bottom.

Step 2: If the above method does not work, follow the second method. Press the del button on boot to see if you can enter the BIOS normally, if you can, it means that it is unusable due to system reasons, and reinstall the system.

If pressing the DEL key does not enter the BIOS normally, then there is a problem with your motherboard mouse interface and send it for repair.

If the computer mouse does not respond, this may be your computer, which is not turned on normally, and there is another possibility, you are using a wireless mouse, is the wireless mouse out of power? Give it a try with a different battery.

Dear, for you to find out that the computer keyboard and mouse are not responding to the operation of the computer method: 1. If all the keys are out of order, first check each key on the keyboard, there may be a situation where the keyboard is pressed down and the other keys are not responding. If the keyboard is damaged, it may be that the keyboard is aging or the circuit board inside the keyboard is dirty, which will cause the keyboard to malfunction due to poor contact, in this case, it is recommended to replace the keyboard with a new one.

Anyway, the keyboard is not very expensive now. 2. Check whether the keyboard interface is loose and the contact is poor, if the user understands how to use a multimeter, you can use the multimeter to detect whether the computer keyboard is damaged. 3. If the keyboard is normal, it means that it is a computer system problem, and we often say that the system is repaired under the installation mode.

First of all, turn on and hold F8 and then press Enter to fix it. Then exit safe mode and restart your computer to fix it automatically. Of course, if the keyboard still fails, we can restore the system to a time when there was no keyboard failure.

4. If the fault persists, try to open the Command Prompt (AMD) command, then enter the sfc scannow command on it, and then plug in the original system to repair the system to automatically repair the system. 5. Try to enter the BIOS to set the CD-ROM drive for the first boot and insert the CD-ROM drive in the repair installation system. 6. Of course, it may also be the fault of the floppy drive, and the driver is not installed, the solution is to use the driver wizard to automatically detect whether the driver is normal.

7. The registry is corrupted and needs to be repaired. The solution is to click the "Start" menu, click "Run", enter "regedit", open the registry, enter "hkey local machine system controlset001 control keyboardlayouts", there are many children in it, through observation I found that ending with "0804" are Chinese Simplified Chinese input methods. Open "e00e0804", immediately see that there is a "layoutfile" sub-item in the right sub-item, double-click to open the item, and change the "to" in "numerical data" to "OK".

And so on, we can change all the "layoutfile" in all the children ending with "0804" to "", which is selected according to our commonly used input method. Finally, restart your computer.
