Bottom corner of my screen keeps going dim at random times

[Tireoghain]

Hi, my laptop only recently started having a problem in which the bottom right hand corner of the screen would go dim. It mostly happens at random times. I could be watching a video for 15minutes and then the bottom right hand corner of the screen goes dim and stays dim for a while and then it will just fix itself. This can be really annoying as you can guess, as it can stay dim for quite a while at times. Ill attach images so you can see what it is like when being dim (first image) and normal (second image).

Also i seemed to have lost the screw at the back which held the disc drive in place, is there somewhere in which i can buy this screw? 

Thank you!

Hi! @Tireoghain, 

Does the issue persist on the BIOS page?

Were there any physical damages to the screen?

Have you tried checking with an external monitor does the issue persist?

Try updating the windows to the latest version.

If the issue does not persist on the BIOS page try updating the graphics driver and BIOS on the PC to the latest version.
