Thanks for providing the picture of the keyboard and the errors - that's a huge help!
***Keyboard:***
Honestly, looking at the visible age and wear of the keyboard, I'd guess from experience (professional IT engineer that has troubleshooted a loooooot of machines) that its likely just the keyboard module/keys on it wearing out. Especially as a number of those are commonly and visibly on this machine, higher use.
Have you ever in the life of the device spilled anything on it, especially in that area?
***Graphics Driver:***
Does the error message contain any additional information at all?
I'd try re-installing the GeForce Experience and then the install if you can, then it looks like this doc from Nvidia seems to help pull logs on that error.
***Note: While those steps seem reasonable and appear to be from Nvidia support, anything touching registry or drivers can have risk for your machine, and any/all changes, maintenance, troubleshooting you perform on your machine is at your discretion and risk.***
That bit said, I'd likely pull the logs and get more detail than the generic "An error has occurred" GeForce gave you above. ******
Best of luck, and please let us know if you get progress on either of those! ******
