Screen flashing and going black

[BridgetteL]

Randomly my screen flashes. And now my screen is blacking out. I can't duplicate the problem, it's random. I'm ready to take it for service. Wherever that would be.

Hi@BridgetteL, Welcome to the HP Support Community!

I understand when you power on your laptop the screen keeps flickering on your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Does the issue persist in BIOS?

As you mentioned when you power on your laptop the screen keeps flickering on your laptop.

If the issue does not persist in BIOS try updating the graphics driver and BIOS on your PC.

Try performing a BIOS default on your PC and check if it helps.

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Also, Uninstall the graphics driver from the device manager and install the latest drivers and BIOS from the links below.

Link to update the BIOS.

Also, update the graphics driver using this link.

You can try updating the drivers on your PC using an HP support assistant.

Refer to this article to know more information about using HP support assistants.

Refer to this article to further troubleshoot display issues with your PC.

If the screen is flickering in BIOS, it is certainly a hardware issue with your PC.

Hope this helps! Keep me posted.

I'm sorry it took so long to get back - I had a death in the family.

I tried to uninstall the graphics driver, but I can't seem to locate it in the Device Manager.

Also, the bios update you provided is apparently blocked by this device. 

And, the link you provided for the graphics update, I got an error stating that my computer doesn't meet the minimum requirements.

I did a bios default, but my screen still randomly blinks. I haven't spent enough time in bios to see if it continues there as well. I will do that now for a time, and wait to hear back from you as to why the bios and graphic links won't work for my computer.

1. Turn off your HP laptop.
2. Disconnect all external devices (printers, USB drives, etc.) from your computer.
3. Remove all recently added internal hardware.
4. Press the Power button to switch your HP laptop on.
5. Once your unit starts booting, immediately press the F11 key. Repeatedly press it until you see the Choose an Option screen.
6. Select Troubleshoot.
7. Choose Reset this PC.
8. You can either opt to keep your files or to remove everything.
9. Select Keep My Files when you want to retain your data. Once you click Reset, your operating system will be reinstalled. The process may take a while.
10. Choose Remove Everything when you want to remove all your personal files.
11. You can opt to remove everything solely on the drive where your operating system is installed. On the other hand, you can click All Drives when you do not want to retain any data.
12. You can also fully clean the drive you selected or just remove your files.
13. Click Reset.

After I reset. Do I have to do anything else? Like update drivers?

Hi@BridgetteL,

Drivers will automatically install the and the operating system will also be up to date.

[BridgetteL]

Okay thank you.

I'm hoping this worked.

I have done all the steps, including the resetting of my computer and I am still having problems. Now there is the occasional "static" bar that goes from side to side. So I am assuming at this point that it is a hardware problem.

What do I do now?

Hi@BridgetteL,

We have done the basic troubleshooting as per the document and the notebook needs to check to get to know its hardware is faulty, not a software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
