i don't think the 7800 is a UEFI enabled bios, as such many newer video cards will fail to work if HP mad the same mistakes that other venders did which prevents the bios from switching from uefi video to legacy video mode


due to this only video cards up to nvidia's 600 series will work and because you have a "SFF" system using a custom power supply only LOW PROFILE VIDEO CARDS THAT DRAW 70 WATTS OR LESS WILL WORK


bottom line, replace the system with a newer one that has uefi support, and do not get any "SFF" based system, you want a system that can take full height cards
