The display is red, the screen is not on, and the computer display is red

First: Check whether the connection between the computer host and the monitor is loose or damaged, and whether the monitor is normal.

Second: This is the most common fault, where the memory module has no signal due to poor contact. Solution: Power off/unplug the memory module, polish the gold finger with an eraser and then put it back in.

Third: the graphics card is in poor contact with the motherboard (discrete graphics card), and the solution is the same as the memory.

Fourth: the power supply is broken. Although you can hear the main unit working after booting up, the processor part is no longer powered or the power supply is insufficient (insufficient power), which causes it to fail to start normally. Workaround: Replace the power supply.
