Hello friends:

Judging from the above description: due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, the memory and the memory slot are in poor contact, and the graphics card and the graphics card slot are in poor contact, resulting in a black screen and inability to boot.

Solution: You can turn off the power first, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) wipe back and forth a few times, and then insert back into the memory slot (or insert back into a memory slot), it's OK, if there is an independent graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install the machine, restart the computer and it's OK, (take the memory ** as follows:)

How to solve the black screen of computer boot caused by computer hardware failure.

1. The monitor is not damaged. The first thing we need to look at is to see if the monitor of our computer is burned out.

2. The computer host is faulty. Faults such as damaged host power supply, excessive overclocking, and incorrect CMOS settings on the motherboard can cause a black screen and flashing cursor on a desktop laptop, so it is important to troubleshoot these issues first.

endHow to solve the black screen caused by a non-hardware failure.

Restart our computer. If you can't see or see the start menu, then we can press the shortcut key to restart the computer (Ctrl+Alt+Del or Win+R), of course, if you really won't restart, you can press the host switch, turn off the computer and turn it on again (this is not recommended).

Then after the computer display light is on, keep pressing the F8 key until you enter the safe mode, then enter the desktop from the safe mode, and then disinfect the computer.
