Windows 10: PC not boot up immediately stuck in Black Screen with short white line

My PC wont boot up as fast as before, it will stuck in the black screen with white short line for few seconds or longer only the boot up image will show. how can i solve this issues?

:)

 

Screen stuck in black and white

I have a Lenovo Flex 4 Windows 10 laptop. Additional specifications are listed at the bottom.

I have a very strange problem. My account seems to be stuck in black and white. When I boot the computer, the lock screen is in color. When I log into my account, it is in solely black and white. When I log into another account, color is restored.

I am at a loss. I booted into safe mode and the issue was not resolved. I know it is not a hardware problem, as color would then not appear anywhere.

If anyone has any advice to offer, it would be much appreciated.

EDIT:

I have not found a solution to the problem yet, so the temporary solution I found is to just use another account. Although I don't believe this to be a permanent solution, I am growing increasingly frustrated with using a computer with a black and white screen.

If anyone has any ideas, please let me know. Thanks.

Edit 2:

One more thing which I forgot to mention is that the screenshots appear in black and white. I have tried resetting both of the graphic card control panels to factory defaults, and have also tried fully uninstalling and reinstalling both drivers.

dwm.exe - Black and White Screen

Last night I was using my PC as normal, and went to copy something with CTRL+C. I think I accidentally pressed another key in the process, though (either X or V). Immediately after, my screen turned black and white. I tried restarting, and that did not resolve
my problem (screen was still black and white), so I started to dig deeper. I discovered how to create the problem, and how to stop it. I stopped it by ending the dwm.exe process in Task Manager (This is a Microsoft process, it seems). The process immediately
opened again, but the error didn't occur. All was fine until I went to open my recording software, Dxtory. When I opened it, my screen immediately went black and white again, and remained that way until I ended the dwm.exe process.

Some important things to note:

• I'm not sure if this is a Windows error or a Dxtory error. I've updated Windows (build 16299.19) (Updated before this started occuring), Dxtory (2.0.142), and my Nvidia drivers (387.92).
• Screenshots are black and white as well.
• When I open a program that requires administrator permissions, the prompt is the correct color, even if everything else is black and white.
• This effect is not on the login screen, although I'm not sure if it occurs on other accounts.
• It seems like there might be multiple things that cause the issue, and Dxtory is just one of them (For example, when I logged onto my PC this morning, my screen was black and white, despite Dxtory not being opened)

Can anyone help me? Thanks.
