Hi, 
I have a problem with my laptop. 
Model: Aspire 5740g
Changed: 8gb (4+4) ram and Sandisk 240gb SSD. 

Laptop is not boot on windows and there is no display on screen. When I tried external screen I saw 4 wide vertical pixel fault lines. 
I've tried ubuntu OS and laptop boots normally but pixel fault lines exist again. 

How can i fix it?
