There are two vertical lines on my screen that do not go away.

@Montag1 Here's the best way to identify the issue and resolve it accordingly:

• Check if it works fine on an alternate monitor, if not available, check the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the alternate monitor or the BIOS (Accessed while tapping F10 during a restart for HP computers) it's a software issue & I suggest creating a new user account to check if that works better, for starters or contact the manufacturer or the desktop for support,
  • However, if it doesn't work within the BIOS or the other monitor either, I'm afraid it's a hardware malfunction.
