HD 7850 Graphics card not recognized by computer!

[acoustics05]

I recently built a new computer but when I tried it for the first time, my graphics card wasn't recognized by my computer. The card is a Sapphire Radeon HD 7850 2GB OC version and my MB is the MSI Z77A-G45. I have already tried disabling the onboard card and restarting, but when I switch the connectors, the computer doesn't recognize the new card. Any suggestions would be appreciated...Thanks!

You are plugging power from the PSU to the card? Monitor cable attached to the card not motherboard?

Is your power supply capable of running the card?

Did you press the card in the slot all the way?
