Your monitor is crapped to the bone. (Or the bar, in that case)

It's broken, the screen capacitors (it might be the capacitors) might have gone out, causing the lower screen to be broken, but if it were just because you went on omgpop, they will have been experiencing tech difficulties.

If it doesn't happen when you boot your computer, then no, it will go away.

But if it happens all the time, you need to get a new screen.
