I see that you are getting colore lines on the screen hiding half of your LCD screen, Please see steps below.
*Turn your Laptop OFF.
*Once Turned OFF, Turned the Laptop back ON then keep on tapping F2 on your keyboard.
*By Tapping F2 on the keyboard this will bring you to the BIOS screen, once in the BIOS of your Laptop and the Colored Lines are still present then the problem is the LCD of your laptop and may reuire replacing.
*If the Colored Lines are not present then the Problem would possibly be the connection of the Video Card to the LCD or the Video Card itself.
*Reformatting Windows can be one of the steps to be done to find out if the issue Colored Lines will be fixed or not.
keep teh laptop away from devices that create a magnetic interference
take the laptop into safemode and check whether the lines are there
reinstall the display drivers check by connecting an externa;l monitor so that you will come to know whether the issue is with the LCD or with the graphics card
turn off laptop. press and hold on the D then press Power button. during the LCD BIST test check if the black line down right side of the screen is visible. if yes LCD needs to be replaced. if not connect your laptop to an external monitor check if the black line display appears to the ext monitor, if yes uninstall / reinstall video driver if fails replace video card or if it is built in replace motherboard.
if no ext monitor available then run PSA (press and hold Fn key then press Power button)
check if the black line is visible. Check also in BIOS is black line is visible, if yes then uninstall reinstall first the video driver if fails replace LCD.
