Ok, I have a problem and I don't know what it could be.Here goes my laptop will power on and boot up to windows and even let you logon but after a little while I'm talking about 5 or 10 min the screen will go out of adjustment as if my settings for my video were wrong i can'y really see what i was working on,but can if you understand what I mean the fan cuts on alot,if I move the laptop just like bump it a little it will also mess up the graf. Any ideal what could be the problem.
