Solved: monitor issue?

My power went out the other day and my computer popped off immediately. But it was what seemed to be a spike because it came right back on. Well my monitor wouldn't come back on so I thought it went out. Well I got it to come back on but now when it does before the os comes on there's a black and white line on the screen like a white line right down the middle vertically. with a black border. the monitor seems to work fine. But what could be causing this and is it normal?

 

42 try to degause your moniter and it may get rid of the line

 

I did that already and it didn't work. I'm not sure what will work.
