White pixels and black lines appears randomly on my screen

[Carrie06]

Hello 

Since a while I have this problem : 

It shows on other colors as well. 

When I put my mouse on it disappears or moves.

The HP support assistant says that everything is updated already.

My pc is only 2 month old, shoul I use the warranty ?

Thanks in advance

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• 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.

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. this sounds like hardware related issue with the Display and in order to fix this issue,  your computer needs to be serviced.  As we have limited support boundaries in the support community as of now. 

I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically.  HP Support can be reached by clicking on the following link:  www.hp.com/contacthp/​​​​​​​
