Maybe making the text easier to read might help.

Anyway, i think there's an issue with the pci-e power.

The 7900 and 270 use a lot more power from it compared to the 210.

DId you try another pci-e slot if that's availible?

 

edit: after some more struggle to read. If i understand it correctly, it's an hp pc pre-build thing?

what do you mean the board power? it has a 6 pin plugged into the card I figured it doesn't matter?

Well every component you plug in get power and data from the pci-e slot.

The power comes from the small part at the left of it that every pci-e slot has.

The right part, that can be different sizes, are the data channels.

Well then that's the issue. HP hardcodes in the BIOS of their motherboards that the pc won't boot unless a handful of specific gpu's are present, if that isn't the case. It won't boot.

So, it won't boot because the bios detects a gpu that isn't in it's whitelist. It's very common in prebuilt pc's.
