My omni 100 pc was on and suddenly starts flashing red blue green grey and white. I can hear sounds as if all is well on the background but can't see anything but these colors

Hi @annmark172,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here? Learn How to Post and More.

I see that your desktop's display is experiencing some image-quality issues, and I would be happy to be of assistance! To begin, I will need to ask you a few questions:

• What is the Product and Model Number of your desktop?
• Is the power cord securely plugged into the computer?
• Did you install any new hardware or software recently?

Next thing, I would suggest here is to boot the computer into the Bios screen and check if the colored horizontal bands are visible or not.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your PC, as it is starting press the  F10 button repeatedly

Once you are in the BIOS, if the horizontal bands are still present, it is likely a hardware failure. The next two steps may resolve the issue. The first one is to do a hard reset. I have included the document 'Performing a Hard Reset or Forced Reset'. The next and final step is to perform a BIOS update. I have included the information here for you 'Updating the BIOS' as well as updating the graphics card drivers from our HP Support website, using this link.

Next thing, I would suggest here is to Run the test on the graphics, display or video from F2. (Please capture the failure ID for further assistance).

Please respond to this post with the details and the result of the troubleshooting for further assistance. 

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world

Available and ready to help.

Thanks for the information Jeet, but when I turn on the computer I can't see anything but the flashing colors, so I'm unable to do all the stuff recommended to do. The PC was originally a window 7 but about two years ago I upgraded to window 10...this was a free upgrade from Microsoft.

Hi @annmark172,

Thank you for replying,

I appreciate your time and efforts,

As I understand you are unable to perform anything on the computer due to flashing colors, I Just wanted to check what happens when you boot the computer to the Bios, do you still see the flashing colors, If so, this is definitely a hardware failure.

I would personally suggest you contact our HP phone support for available service options. If your product is out of warranty, please choose paid options to get the tech support number.
