I bought my laptop in July and since December the screen has been blurry with lines: 

After the laptop has been on for a while it heats up dramatically and begins to flicker before looking like this: 

After which it fully goes completely black: 

I then hold down the power button for 30 seconds and attempt to reboot, here is a video of that whole process:

I then attempt to reboot again, here is the second reboot attempt video

The screen then looks like this: 

I then:

       1. I then hold down the power button for 30 seconds

       2. Press the window key and B before pressing the power button 

       3. The screen remains as the picture above 

       4. I repeat steps 1 – 3 for 10 minutes until the login screen comes back up and looks like this: 

I use this laptop for Uni so I don't have any complex programs on it. Also, I have HP support assistant so I know all my drivers are up to date. My laptop still has a six-month warranty so should I send it back? 

Thank you in advance for the help

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.
