Press the three keys in the figure at the same time, and then press the DEL key to enter the BIOS to set the system disk to be the first to boot. F10 Enter.

There was an error with the system, reboot the hard drive or reinstall the system.

Press and hold the power button and don't move, and it will turn off after a while. For desktops, it is recommended to tighten the wire to prevent bad contact, press and hold the F8 key when the boot menu appears, select the last correct configuration, and enter to try. If it doesn't work, you restart it again, the menu appears to select the safe mode, enter the antivirus, 360 guard scanning, and after processing, restart to try.

I can't get into the reinstall system.

Press F4 in win10

A Samsung 17-inch flat in my unit also had such a problem. When the machine is turned on, it flutters, as if it was touching electricity.

Later, it was found that it was damp.

The monitor is fine, I know there have been cases before, you can plug and unplug the CPU signal cable. If it hasn't been reflected, then unplug the graphics card with a leather eraser, polish the gold hand paper, and then wipe it in, restart the computer monitor to display normally, troubleshooting!

Most likely it's a problem with the system, is it new?

This is a problem with the computer system, so I'll take a look at the computer repairer.

Hello. The color of the power light is always green, is it flashing?

If not, it should just be a problem with the backlight circuit, check the high-voltage board circuit.

If the green light also flashes, it is possible that the power belt will not move

Check that the cable between the graphics card and the monitor is loose.

It's really broken......Probably a switch.

It's also possible that there is an issue with the graphics card of the console.

If the screen of the monitor is broken, it is basically useless, and no one will fix it for you, because the price of repair is the same as the price of a second-hand one.

Hello to enter the monitor menu.

Find Language, then OK.

Select Chinese to OK.

Exit for reference.
