After the computer is turned on, the F1 interface flashes and the screen goes black, and the machine

First detect whether it is caused by a soft fault Through CD-ROM, start the system with the system disk to see if the fault disappears; (Caused by the loss of the boot file or the infection of the virus.) In this case, you can reinstall the system with the files required for backup, otherwise you can detect whether the hardware device is working properly such as graphics card...

If the hard disk indicator does not light up, it means that it has not been booted from the hard disk, you can check it like this, enter the BIOS, and see if you recognize the hard disk, given that you have not been on the machine for a long time, it is unlikely that the hard disk will have problems.

Generally, if there is a problem with the keyboard optical drive power supply, it is likely to be a problem with the South Bridge, and if you are in the insurance, you can go to the after-sales service and hand it over to the after-sales service to solve.

If it is out of warranty (unlikely) you can find a maintenance point to test it, if the south bridge is welded, it will be about 100 yuan for a welding. . .

That's a problem with the graphics card, you can remove it and wipe it, if it doesn't work, you have to replace it.

Enter the BIOS to see if the hard disk drive can be detected, and there are white words on the black screen, whether it is Ctrl+Alt+del or not.

Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact. 3.If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

The screen has been flashing after the computer is turned on, and then the screen is black, this situation is mostly due to the display and the graphics card, you can first check whether the display is not connected badly or try to change the monitor, if the problem is still the same after changing the monitor, then you have to check the graphics card, you can detect it by replacing the graphics card.
