Vertical lines on display

When I have some software open, there are always some vertical shadows on the screen.

Thank you for posting on the HP Support Community.

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?

let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.

There was no issue in the BIOS screen. The issue has existed for several months. The display on the external monitor functioned fine without issue.

Let's try these steps -

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. 

Download and install the BIOS, Chipset drivers from this link.
