Graphics chip heating up causing wavy lines on screen

[BK777]

My monitor has wavy, vertical lines.  I was told that it is because heat is affecting the built in video graphics chips  I bought it a year ago in July so it is out of warranty.  Is there a way to fix this issue?

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, 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.
