Why does my computer peak hold a blue column going down it? And how can I take rid of it?

Answer:

If it's an LCD blind it might've been puncted within. It it's not, or even if it is, it might be stuck pixels. Is it there while it's sour too? It could be lag, or plentifully of other things. Try another moniter and if it's still there, relocate you're desktop background and do smaller number things and have smaller quantity programs open at indistinguishable time.
