I understand you are in need of support with the colorful screen & it's gibberish characters,

I'll be glad to help you out, however, for an accurate solution I will need more details:

  • Have you attempted any steps on your own before posting on the HP Forums?

  • Did you check if this issue occurs on an alternate monitor?

Please reply with the details for further assistance.

Afternoon, I'm under the impression that the video card may have come loose from its slots assuming the card is dedicated. If the card is not dedicated then there is a delivered issues with your setup. Check the DirectX version and follow the test protocol for testing the DirectX system nd driverr.

Although I posted a link that explains how to check your DirectX version, there is a test protocol involved in running this test. If the test returns successful  then the video driver could be going bad. One thing that would help with his is if you have a secondary  video card to fall back on, make sure your system has the capabilities to run the new or used card successfully until one can determine what is wrong with the correct video setup.

Please read my comment above once more, I suggested that you will need a secondary video card in order to verify what DirectX version you have along with being able to check your system there after. According to your comme ts you've checked the system with multiple monitors, in doing so has any of the pins/leads become bent or broken.

 

EDIT

 

It is apparent that the truth comes out. If one is unable to connect a key board or mouse to their system, I would suspect that the mother board is toast.
