What should I do if the computer can't enter the system?

1. If the computer cannot enter the system after starting, you can try the following methods: check whether the computer hardware is normal, such as whether the hard disk, memory, graphics card, etc. are plugged in. Try to enter the safe mode, press the F8 key or other shortcut keys to enter the safe mode, and then repair it.

2. After booting, you can press F8 to see if you can enter the safe mode, or the correct mode for the last time. If you can enter, it can be automatically repaired later to solve the problem that the computer cannot enter the system.

3. Method 1: Restart the computer. First of all, if your computer cannot enter the system, you can try to restart the computer, which can usually solve most of the problems. Press the power button and wait for the computer to turn off automatically. If your computer doesn't respond, you can press the power button for a long time to force the computer to be turned off.

4. Check the hardware connection: First, check the hardware connection of the computer and make sure that all connection cables are plugged in, especially the power cable and data cable. Sometimes a loose connection will cause startup problems. Restart the computer: Try to restart the computer. Sometimes a temporary system failure may be solved by restarting.

5. Before entering the operating system, you should press the F8 button, then select the last correct configuration, and then press the Enter key. You can consider reinstalling the system. Before reinstalling the system, please make sure that you have available Windows installation media (such as DVD or USB flash drive) and all important data backups.

What should I do if the laptop can't enter the system when it is turned on?

1. In this case, you can open the computer case, pull out the memory stick, clean up or replace it. If there is a problem with the hard disk, first check the bad channel of the hard disk. If there are a large number of bad channels in the hard disk, it is recommended to replace the hard disk. If there are fewer bad channels, it is recommended to format the partition disk and then reinstall the system.

2. You can press the power-on button for a long time until the machine is out of power, then turn it on, and then cut off the power, repeat 3-5 times until you enter the recovery mode as shown in the figure below. 2 From the selection option screen, click or click the difficult solution

3. Restart the computer. If you can enter the system normally, it means that the last time was just an occasional program or system operation error, which is irrelevant.

4. Reset the BIOS settings: try to reset the BIOS settings of the computer.You can restart the computer by removing the CMOS battery (usually a button battery) on the computer motherboard, waiting for a few minutes before reinserting the battery, and then restarting the computer. This will restore the BIOS to the default state, which can sometimes solve the startup problem.

What should I do if I can't enter the system after the computer is turned on?

1. Check whether the computer hardware is normal: check whether the computer has abnormal sound, light, etc. If so, it may be a hardware failure and needs to be repaired or replaced. Check the boot order of the computer: Check whether the boot order is correct in the BIOS settings to ensure that the hard disk is the first startup item.

2. If the computer cannot enter the system after starting, you can try the following methods: check whether the computer hardware is normal, such as whether the hard disk, memory, graphics card, etc. are plugged in. Try to enter the safe mode, press the F8 key or other shortcut keys to enter the safe mode, and then repair it.

3. How to deal with the computer startup that cannot enter the system: check the hardware connection, restart the computer, enter the safe mode, repair the startup, and restore the system. Check the hardware connection: First, check the hardware connection of the computer and make sure that all connection cables are plugged in, especially the power cord and data cable.Sometimes a loose connection will cause startup problems.

4. Solution 5: Reinstall the system on the USB disk. If the above methods cannot be solved, we can only adopt the ultimate solution: the USB disk installation system can solve 99% of computer software failures. Use the USB disk boot disk making tool to make a USB disk boot disk, and then enter PE to install the system.

5. The reason why the computer cannot enter the system after power-on Startup order problem: In the BIOS, we can set the boot order of the computer. If we place optical drives, USB flash drives and other devices before the hard disk, the computer will detect these devices in the order of startup, resulting in the inability to start the system normally.

The computer can't enter the systemSolution

1. Restart the computer to solve the problem. If it still doesn't work, try other methods.

2. The inability to enter the system normally is generally caused by software or hardware failures. There are many and complex reasons. It may be that the system file is damaged, it may be a virus infection, or there are too many background self-starting programs or multiple security software installations that cause the system to die, or it may be the graphics card or internal There is a problem.
