3. If there is still a blue screen after deletion, or you can't enter the safe mode at all, then reinstall the operating system and try it.

4. If the blue screen is still blue after reinstalling the system, the hardware problem will be considered. First of all, clean the dust inside the computer thoroughly, and remove the memory, graphics card, and PCI slot.

Remove the device and test it with an eraser. Because the temperature caused by dust is too high, poor contact, etc., it will also cause a blue screen; At the same time, the CPU, graphics card, etc.

Remove the fan and replace it with a new heat dissipation silicone; Also, check that the temperature of all hardware is normal.

5. If it still doesn't work after cleaning the computer, then use the replacement method to check the computer hardware, if there is no replaceable hardware or you are not familiar with the computer, it is recommended to find a specialty.

Handled by maintenance personnel.

6. Hardware replacement is troubled in the following order: memory, hard disk, graphics card, motherboard, power supply, other hardware, and CPU.

If it's just a single time, you'll be fine after a while, maybe you've deleted a file or accidentally changed a setting.

It prompts you that if you have this problem for the first time, it is recommended that you restart it, if it still appears, check your hard disk, if you still appear this interface, it is recommended that you reinstall the system, if it still doesn't work, it may really be that the hard disk has a problem and you have to repair or replace the hard disk.

Hello: Please check as follows:

1. Check whether the electrolytic capacitor on the motherboard is bulging, if so, you need to replace the capacitor.

2. If not, it is estimated that the power output of your computer power supply is not enough. After the computer is shut down for a period of time, it is difficult to start or the startup process is dead, automatic restart, or some hardware can not be loaded normally, generally there is a problem with the power supply of the host, the output voltage of the power supply is insufficient, and the power consumption of the computer is large when it is turned on, resulting in the voltage dropping, resulting in the computer can not start normally.

If you test it this way, if your computer has hardware such as an optical drive, floppy drive, or recorder, you disconnect them from power, which will reduce the power consumption. See if it can start normally. If you can, change the power supply.

Can't get into the BIOS?

Then there must be something wrong with the hardware, it is recommended to use the master test card to test the problematic hardware, and then replace it.

If you don't have the conditions to test, it is recommended to send it for repair.

1. The main reason is that there is a problem with the settings of the host BIOS, and when the BIOS settings are incorrect, restarting the computer will automatically enter the BIOS.

2. Since it is caused by the setting of the BIOS, then you only need to set it in the BIOS to solve the problem.

3. When the computer is turned on and enters the BIOS, select the options with similar words such as load fail-safe defaults, load optmized defaults, restore defaults, etc., and press "F10" to save and exit after selection.

Changing the system is simple and easy, and all the problems are solved when the system is changed.

If it is found that there is or is suspected to be a fault in the whole machine or individual hardware of the laptop, it is recommended to send the computer to the official after-sales service center of the corresponding brand, and a professional maintenance engineer will conduct a comprehensive inspection to confirm the fault and repair and replace it. The whole machine maintenance, cleaning and upgrading of the brand computer is best done at the official after-sales point of the corresponding brand, and the official after-sales service is used to use the original parts, and the maintenance skills and specifications of the engineer are definitely more formal and assured, which can ensure the quality of maintenance.

The hard drive was not found or the hard drive did not have a system.

Boot card windows welcome screen.

1. Driven by conflict.

1. Press F8 continuously to select the last correct configuration to enter the system, if it can enter normally, you can.

2. Caused by poor contact of the hard disk.

1. Open the case and re-plug the hard disk data cable and power cable.

2. Change the interface of the hard disk data cable to the motherboard and replace a power cable.

3. Replace a good hard disk data cable.

3. The hard disk has bad sectors or the MBR of the main boot is damaged.

Open the partition tool Disk Genius in PE, select the hard disk with the right mouse button, and click Bad Sectors Detection and Repair.

Use the right mouse button to select the hard disk, click Rebuild Master Boot Record MBR back to the PE desktop, click Windows Boot Repair, and select C drive to repair.
