HP graphics card Update


Recently I upgraded my old GTX 550ti with a new Radeon HD 7850 from powercolor. After I install the new card, there is no display, and there is no post, so I don't think it's even booting.

The old GTX worked fine, so the pci slot is ok. The GTX 550ti uses a 6 pin connector to the power supply, so I think the psu is fine too. I uninstalled all nvidia drivers, and tried to install the new card. No boot. The onboard vga works, so the cable is fine.

The powercolor website indicates, "mainboard could not detect UEFI bios of display card correctly during booting" and recommends a bios update. Referenced from this link (
