After powering on, press the F8 for the last correct configuration

The system is misconfigured, the system has inexplicable symptoms, and F8 needs to be correctly configured for the last time. Haven't played cfIf you cf re-**, uninstall the previous one, install it in a different place.

See if there's a problem with the keyboard.

1. The black screen cannot be turned on, which is generally due to poor contact of memory or graphics card or memory quality or power supply problems or poor CPU contact (no sound or beep sound when booting up, more than two sounds, one sound is normal).

2. Generally for re-inserting the graphics card and memory card, the most important thing is to clean up the dust near the CPU and memory, which is the easiest way to do this - or replace the memory or graphics card or power supply.

3. The capacitor on the motherboard may be bursting, see if the capacitor near your computer's CPU (the capacitor erected like a small bucket) is bulging, and the normal one should be flat.

Press F8 when you boot up, and then enter the screen Generally in Chinese The last correct configuration.

In English, the last is the beginning of the same.

After pressing the host switch, it will not stop after powering on, and you can press the F8 button for a short time.

Or wait for the motherboard to tick and the display starts to light up, and then press it later.

Select the last correctly configured method:

1. Restart the computer and keep pressing the F8 key;

2. After the startup item prompt appears, select the last known good configuration (English: last known good configuration) and press enter.

The last correct configuration is that the boot program reads the setup data that was retained for the last normal operation of the system before you entered the BIOS.

Normal boot is when the boot program reads the last data that the system retains before you enter the BIOS and boots.

If there is no problem with the computer, it can generally boot normally, if you encounter a system crash or a blue screen or black screen and other system configuration conflicts or incompatibility, you can choose the last correct configuration to boot.

A normal start is a normal start.

The last correct configuration means that a backup of the current configuration is kept every time the system boots up normally. Once something goes wrong with the system, you can use this backup to restore it.

For example, after a certain startup, you install a software, and then restart, because of the problem of this software, the system cannot enter and crashes. Well, after f8 with normal boot, how many times is it a crash because the system has been destroyed. However, F8 uses the last correct configuration, and Windows will boot with the last time it was backed up and booted normally.

In this case, it is possible to bypass the problems caused by installing the software (because the system was easy to use the last normal boot). But it's not 100 insurance either.
