I have just recently had an issue that I cannot figure out. About a week ago I got home and turned on the computer. The boot screen was fine and so was the login screen. Then as my desktop was loading I had this weird screen set up shown here.


So I pulled the battery and restarted the computer and everything was ok. I been using the computer a lot the past week and today I was playing a game and when the screen came back to desktop it happened again. I restarted it multiple times with no success. Login screen still normal, desktop was still messed up. I had full function of windows (the things I could see). Then I went to plug my laptop in to my TV to run diagnostics on it. When I did this the screen flashed like it always does when I plug the HDMI in and what do you know everything works perfect. Diagnostics came back with everything working fine.

Any advice? I have heard this is a LCD issue and also a video card issue. I dont mind fixing it just want to know what to fix.

If you're seeing the issue on both the LCD and an external monitor than the issue is the video card.


If the issue is just with the panel and doesn't transfer to an external monitor it is with the panel.


Sounds like your issue is with the panel.  It would be very unusual for both the monitor and video to go out at the same time.


I'd suggest updating the video drivers as a first step.


Another thing to do would be to move the panel back and forth when you have the issue and see if it changes or clears.  If it changes or clears then you can be pretty sure that the panel is the problem.
