Mysterious grey bar on computer screen

[angeisnothere]

I had this computer for three years nows and I have take care of it and made sure that nothing traumatic will happen to it.

Just today I have noticed there is a almost translucent green-ish grey bar on my computer screen when I was turing on my computer. At the same time, my computer refused to turn on properly so I had to manually restart the computer thinking that the bar was something being caused by it. I turn it back on to see that it is still on my screen.

If I put my cursor underneath it, I could still see it but the bar will be more green than grey. I have also taken a screenshot of my computer, paste it on photoshop and scale it down to see if it is was deeper than the screen itself and the picture came out like a normal screenshot will and green-grey bar free too. So far, it hasn't gotten larger but I'm worried to see if it will affect my computer negatively in the future. 

If this is just a problem with my screen and not with the actual computer itself, then I would want to know if this is just an easy thing to fix. I'm currently in uni and this week is finals week so I'm worried to see if it is harmful and will be bothersome. Thank you in advance for any tips on this.
