Brightness Buttons Not Working

[Cathal_Roche]

The brightness of my screen won't change and is stuck on an annoyingly low brightness. Both the buttons and the actual slider that you can use to change the brightness in settings don't change the brightness.

I tried changing my display adaptors to Windows Basic Display Adaptor (cause Google told me so), but I've 2 display adaptors and only one of them show Windows Basic ,, ,,.

The first display adaptor let's me choose from; *2 versions of AMD Radeon (TM) 535DX or *2 versions of AMD Radeon (TM) R7 M340.

The second let's me choose from; *3 versions of AMD Radeon r5 Graphics or *Microsoft Basic Display Adaptor. 

I have no idea which ones should be enabled or not,  as every time I tried to change to a different display adaptor, the installation failed. 

Any help would be appreciated!!!!

Neither worked unfortunately... Both downloaded and looked to install something, but nothing has changed. 

I feel like it has something to do with my display adapters because a little yellow symbol is popping up in front of both of them. I wish I knew more about this stuff!!

(Also my fan is running super loud I don't know if there's any link)

SOLVED. I double clicked on one of the display adaptors, clicked update driver and let windows choose a file itself. Then both display adaptors updated to the ones they should have been!!
