Question Why does computer beep 5 times and has error d6

[Bentley1002352]

hi, i have just turned on my computer and it beeped 5 fast times and showed post code d6 on the motherboard. the motherboard is a Asrock 970extreme4 and my graphics card is a zotac geforce 9500gt. The cpu is a AMD phenom II. i have tried manually resetting bios because i cant see anything on screen and the cable is not faulty neither screen because i tested them with other computers. if you have any suggestions that would help alot, thanks.

both point to missing or unrecognized VGA card, make sure it's seated properly

Could be a simple dead GPU considering its age. Have you tried installing the GPU in other systems?

Also possible that a simple cleaning of the golden contacts will make it work. Bit farfetched, but can't hurt while the system is out anyway.
