GTX 645 not working. Computer is doing beeps when I launch it.

[Morfeer]

I want to put a gtx 645 on my computer, I don't know why but whne I launch the graphic card inside my computer it does beeps. 1 Long and 2/3 short. Is it my BIOS who is not compatible with the graphic card? 

What should I do?

Thanks for taking an interest in the HP Support Forums! After reading your post I see that you are getting beeps after launching graphics card. I would like to help you out with this issue today.

Recover the BIOS.

• Turn off the computer.
• With the computer off, press and hold the Windows logo key    and the B key at the same time.
• Still pressing those keys, press and hold down the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows and B keys until the BIOS update screen is displayed or until you hear a beeping sound.
• After the BIOS is recovered, a Continue Startup button displays and a timer counts down. Click the Continue Startup button to restart the computer immediately. The computer will restart automatically when the timer reaches zero.
• When the computer restarts, a black screen appears with a message similar to the following:
• A system BIOS Recovery has occurred. 
• BIOS Recovery (500) 
• Enter - Continue Startup
• After restarting, Windows may display a message stating that the computer was improperly shut down or that a boot problem was detected. Read and respond to the screens to continue.
