So I searched the threads and I can't find my exact problem. Hopefully someone here has the answer. For two days my shift and enter key stopped working (I didn't realize how much I used the enter key til I didn't have it). Then all of sudden it was fixed. Both times it happened while I was using the computer. No liquids spilled or any drops. Now, it will randomly start trying to type periods and won't stop. Has anyone else had this problem? I've tried restarting and hard resetting. Thanks guys.
