I just bought a new dell laptop with windows vista. This morning just as the market opened, the screen went blank except for a small 1 by 1 inch square with thin lines in it in several colors but mainly red and blue thin like. I had to restart my computer from scratch and this took a while. This happens once in a while and at least twice so far when I'm looking at quote tracker. Can anyone tell me what is going on and is there any way to revive the screen without starting over. Thanks for any replies.
Thanks for all of the replies. Will try the f8 thing. Hasn't happened since I started this thread but I'm happy about that.
