Ok, so I have an HP Pavilion Elite m9715f Desktop PC, and I want to upgrade the GPU to a NVIDIA GeForce GTX 750. I have one currently, it fits, and the BIOS splash appears, but it is frozen on that. I got the graphics card mentioned above on clearance, so I thought it was a faulty one that they were trying to re-sell, but to be sure that my computer is compatible with it I am asking here.
