HP Laptop screen randomly flickers

[DestinyL]

This has only happened once before, so I let it go the first time thinking it was a one time occurrence but it happened again today. During my zoom class (same class and time as it happened before, coincidence?), my laptop screen started going out. I don't really know how to explain it but the left half of my screen went green and the right side pink, but I could still hear the professor so it didn't shut off. I let it sit for a few minutes and the right side of the screen came back on with the zoom call in view but it still had a weird pink cast over it and the left side turned black and a few minutes later a bunch of vertical green lines appeared on the right side. So, I shut off and restarted and it still had a blurry overcast of white and when I logged in it slowly went away. It seems to be fine now, but I'm wondering what this issue could have been caused by and how I can prevent or fix it in future instances. I got this laptop about a month ago; new but refurbished so could possibly be that. It's a HP 15" Pavilion Intel Core i7 if that's of any help. Any help is appreciated!

@DestinyL 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 attaching an alternate monitor to your device and 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
