Hi @Caseyeisenman,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I understand how concerning it is to see unexpected lines on your screen, especially when you've tried troubleshooting already. Let's investigate this further to identify the cause and work toward a solution.

• Do the grey lines appear consistently, or do they disappear or change when you move the screen or adjust display settings?
• Have you connected an external monitor to see if the lines also appear there?
• Do the lines show up during boot-up (e.g., on the HP logo screen) or only within the operating system?

Meanwhile, let's try these steps. 

Check for External Monitor:

• Connect your desktop to an external display. If the lines do not appear on the external monitor, the issue likely lies with your built-in screen or display cable.

Update Graphics Driver:

• Open Device Manager > Expand Display Adapters > Right-click your graphics card > Select Update Driver > Choose Search automatically for updated driver software.
• Restart the system and check if the lines persist.

Test in Safe Mode:

• Boot into Safe Mode to rule out software conflicts. If the lines disappear in Safe Mode, the issue may stem from third-party software or drivers.

Perform a Hard Reset:

• Turn off the desktop, disconnect all peripherals, and unplug it from the power source. Press and hold the power button for 20 seconds, reconnect, and power it back on.

Run Hardware Diagnostics:

• Restart your PC and repeatedly press F2 to access the HP Hardware Diagnostics menu.
• Run the display test to check for hardware malfunctions.

If the issue persists, the problem may be hardware-related (e.g., a failing LCD panel or a loose connection). In such cases, contact HP Support for further assistance.
