@Abby98,

Thanks for getting back to us with the details:

Let's try these steps which should help you resolve this issue.

Perform a Hard reset on the Notebook:

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.
With the power off, disconnect the power cord from the back of the computer.
With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.
Reconnect the power cord and turn on the power.

Next thing, I would suggest here is to connect an external Monitor to the laptop and check if the issue persists:

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure,

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer,

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here

Alternatively, you can try to boot the computer into the Bios screen and check if there is a purple blot on the screen.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the F10 button repeatedly

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS)

This would confirm if it's either a hardware failure or an issue with the graphics card drivers so we may reinstall and update the drivers to fix the issue as mentioned above.

If the issue occurred after an accident (such as dropping it on the floor, liquid spilled on it, etc.) there could be a hardware failure and in such cases, you may need to get the computer repaired via HP (there could be a charge involved if the PC isn't covered by the accidental damage protection plan)

For more assistance, please follow the steps suggested in the support document for - HP Notebook and All-in-One PCs - Troubleshooting Screen Issues (Windows 10, 8, 7)

Reply with the result of the above-mentioned steps, for further assistance.
