    White line upper left corner before startup


    Ever since my PC crashed a couple of days ago, before startup, for like 30 seconds it started with like 5-10 seconds, a white line appears on the upper left corner of my screenNon-blinking. My PC does boot normally after this, but I would like to fix it before it won't boot at all anymore.Does anyone have a fix for this?Thank you very much

    :)

    Small White Square in Upper Left Corner - Cannot Remove

    This is going to be hard to see, but above the left of the recycle bin icon... there is a tiny white square. When I put my mouse cursor over it I get the cursor to change to the activity cursor (spinning blue circle) - I have no idea what application is causing this and have stopped all tasks starting with windows on boot.

    Any ones else ever see this?
