Hi there. I have been searching for a solution to this intermittent problem and most posts don't seem to actually address the problem I have. Mostly people with limited knowledge suggest the obvious or don't really read hat the issue is. So here is the problem: I am trying to fix a friends laptop which is an ASUS X44L. Upon starting the laptop a white screen appears with horizontal lines (NOT VERTICAL). This seems to freeze on this screen unless I move the screen back and forwards or press the bezel on either side at the bottom. So I have done all the obvious things including updating all drivers, cleaning out any accumulated debris, pulling the screen apart to check the cables are OK and all appears to be good. Now this doesn't happen every time and the LCD seems to work perfectly with no other problems that are obvious so don't think the screen is cactus. About to see if I can check the GPU is seated properly. Any suggestions are much appreciated but please don't suggest things like malware as this has all been checked out and the laptop runs smoothly in every other respect. I am wondering if it is something to do with the bios not properly initiating the GPU but its just a guess?
