My screen freezes when my laptop display goes into sleep mode. What is odd is that there are colored vertical lines that appear when this happens. I can not Ctrl ALt Del out, and can only do a hard reboot. I have never seen anything like this and thought that it could be a problem with my screen itself, but I would think that would happen at random times and not just when the screen sleeps. any help would be appreciated, Thank you....
