HP Pavilion Graphics card upgrade

[SlavaMay]

Hello

I tried to install rtx 3070 graphics card into the pc, it fits normally but it doesn't work. Of course I first connected an evga 850w power supply to provide enough energy for the system. The signal just doesn't go to the monitor. The gpu works fine in another pc. 
I tried to find the motherboard compatibility list, but failed. Tbh don’t think that the mobo doesn’t support the card 

Secure boot is disabled and Legacy support is enabled

 Thanks for any help

hi

normally this should be fixed simply with the manipulation you seem to have done

most graphics cards should work, you won't find this type of listing
If the computer does not work with a graphics card, most of the time
problem with Secure Boot
insufficient [edit] Power supply ( wrong translate )
faulty graphics card
incorrectly installed graphics card
need to update the bios
etc
the incompatibility of the card itself is quite rare

not the same motherboard, but this might help

Thank you for your help 

will try to update bios. I also suspicious of the GPU isn’t fully inserted, it looks ok, but probably ordering a pci express riser could resolve the problem
