vertical stripes on laptop screen

[arkila1807]

Wide vertical stripes appear on my screen especially moving objects on the screen, they look like shadows of the objects itself.

I cannot update window10 too: windows update says 'contact your PC manufacturer to see if you can upgrade the system BIOS'.

Can the 2 problems be connected? any advise?

thank you

@arkila1807 Greetings from the HP Community!

Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here

Hello, 

thank you for your help

Unfortunately I haven't solved the problem.

The only thing I found out is that it looks to be a software problem since I don't see stripes accessing the BIOS.

I have tried everything you suggested except the window reinstallation so far. 

Windows doesn't update and the problem now is that I am no more able to enter the BIOS tapping the F10 Key. 

Moreover now the laptop sometime doesn't start unless using the power reset option.

Stripes on the video are still there.

Can be a problem with the BIOS at the root of all my issues?

thanks
