cpu overusage and drive problems

[Lurker88]

hi, my problem is divided in 2 part an i think they are linked:

the first part is that i can t change the light of the screen, i do not have the bar in the settings, the key on the keyboard doesn t work and i can t select the night mode.

the second problem is that every game that i use, indipendently of it s size, it overuse the cpu that goes to 100% and slows everithing.

i thought it was a ptoblem with windows 10 so i asked microsoft and after 3h of trying they told me to upgrade the drivers and ask hp. I tried upgrade drivers but it sais nvidia update core failed.

so my question are:

am i doing the right thing to solve the problem?

if yes, how do i solve the update fail? if no, what do i have to do?

You will see Change Brightness level app open it and there you can change Night mode or brightness.

For the other issues would you let us know laptop serial number of model number.
