PC not Detecting GPU

So I have a pretty ancient computer that I gave to my girlfriend so we could play some games together, its my old desktop which is the HP Pavilion p7-1210.

Most of the PC is original, the only parts I've changed out is the HDD and I put 8GB of ram in it. It still has the stock APU which I reapplied thermal paste to and it has the original PSU which still works fine.

The computer will boot with no problem if I have the DVI cord plugged into the mobo for the Integrated Graphics, but when I plug the DVI cord into the GPU the monitor doesn't appear to be getting a signal. I've checked and made sure the GPU was seated properly and the GPU fan will spin when the pc is turned on. I've tried the GPU in my personal pc and can confirm that it works fine so thats not the issue. I tried looking in the bios for a setting to make it run off the GPU but the bios doesn't seem to have anything like that.

The GPU I have in it is a Radeon 7750 which is a low wattage card so it should work with the psu that was already in place. Anybody have any suggestions to try? Thanks!
 
Solution
Check for a newer BIOS for the system before installing the card. Also an OEM cheap system may not have enough power going to the PCIe slot to power the card, or may have some other issues that don't allow it to work with the card.
In my bios you go to the 'advanced' tab, then 'chipset'. In my bios i can disable the integrated graphics and also check to see that pci-express graphics are now the one being used. I think you should look around in your bios again, it will not be clearly marked, it'll be in a submenu.

The bios for the computer is pretty empty with options, I looked all through it. I found a bios update though that I am going to try out and see what happens.

I found a newer bios for the mobo so I am going to try that, if not I guess ill go with a lower end card.
