Is it Secure Boot that is causing it or TPM. Try enabling just one, then restart and if everything works, than enable the other one.
I had an issue with the TPM whit the the solution being to remove the PIN sign in option and then enable TPM
There is a small vertical line on my monitor and I would like to find out what is causing it.
As you can see, the line is above everything except the mouse
Here are two reviews that I had found
