To be able to answer you effectively, we need some information.

Have you made any changes to your hardware or Os?

• Does this happen (flickering) only in the web browser?

While you respond to that, let's try these steps: 
Bios default:

1. Restart your notebook.

3. When the BIOS menu displays, press F9 to restore factory defaults.
4. Select Yes to confirm.
5. Press F10 to save changes and exit.

Next, let's perform Windows Update and HP Support Assistant:
