Last week I noticed a black line going across the bottom right corner of my screen. After restarting this morning, there are now three black lines. It is not my screen, as it shows up in screenshots and mouse hovers over it: http://grab.by/125i

Recently, my computer has been running somewhat slower as well.

Any help would be appreciated.
