Hi @ankit220695

Welcome to the HP Support Community. 

I'd suggest you try these steps - 

Check for the lines in BIOS - 

1) Shutdown the computer. 
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears. 
3) Press F10 once for BIOS. 

Also, try connecting the computer to an external monitor to check for the lines.

If the BIOS and external monitor does not have any lines, try re-installing the display driver - 

1) In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2) In Device Manager, expand Display Adapter. 
3) Right-click on the Display Adapter, and then select Uninstall device > Delete the driver software for this device check box > Uninstall.
4) Restart the computer. 

Also, try updating the computer using these steps -

Step 1 Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

Step 2 HP Support Assistant Updates - 

1) In the search box, type and open HP Support Assistant. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer.  

Hope this helps! Keep me posted.
