The computer was working fine until a Radeon was added. The beeps immediately start after you plug in the power. 6 long 3 short beeps with flashing red/white lights in front. And is repetitive. I took the video card out and used the onboard GPU with the same results. Have also reseated RAM, CPU, and power supply. Same results. Changed RAM with the same results. Appreciate any help I can get for this.

what is annoying is that for most of the documents consulted, I do not have this frequency
you have for example this
https://support.hp.com/ca-en/document/bph07107
and most are in this type of case, no documents where 6 long and 3 short
i can't help you with this

What type of bios do you have?
Remove everything, leave only one memory module, the minimum to start (if you have more than one module tested then the other)
System disk, one memory module, no graphics card, test
