Computer greyscale/screen loses color.

[Ianmg11]

Recently my laptop screen has been losing all color randomly as if it's going automatically into grayscale/washed out. Unfortunately I know it is not grayscale mode since it's not turned on and pressing ctrl + Windows key + C only slightly changed the darkness of the "grayscale". It has started happening quite frequently and color is restored after rebooting my PC. At first I thought it could've been the drivers on my GPU, but after updating them it still happens. Generally the screen will go completely black for a second and then the screen turns black and white. I really need a solution and I can't just keep rebooting my PC every time it happens. Any help is welcome.

This is almost certainly an indication of failing video hardware -- either the screen or the video chip or both.

You need to connect an external monitor to the laptop.

If the visual artifacts also appear on the monitor, then it is a failing video chip and since those are soldered to the motherboard, they are not replaceable.

If the visual artifacts do NOT appear on the monitor, then it is a failing laptop screen. While those can be replaced, the cost varies enormously by individual PC model.
