Alright. So my down arrow key on my Windows 8 is acting up. Whenever I pressed it, it did nothing. Seconds later, after I pressed it, it would scroll down all on it's own. Help? I can press it, but nothing happens until seconds later then continues as if it has a mind of it's own.

On other note, earlier my whole key board messed up by putting "/.M" every time I hit the space bar. I was able to fix that problem but not the arrow key. Any thoughts?
