Hey, SuperMario1
Thank you for your reply! You answered my question perfectly. However, I probably will not reformat just yet as the problem occurs infrequently and is (temporarily) fixed by keeping the screen in a set position. I appreciate you taking the time to read, research, and answer my problem. Hopefully, it is not a hardware problem because that would just be a hassle.
I clicked "Accept as Solution" because after researching as well, I agree that if it's not a hardware problem, a reformat would be the logical choice.
Thank you again for your response!
