Bios Mods -The Best BIOS Update and Modification Source

Hello, I've seen that the HP Compaq 6000 Pro SFF will work with the Intel Core 2 Quad Q9650.
Unfortunately, all I get is a black screen and no hard drive activity when I put one in. I'm told to update my BIOS, but its already at the latest version (v2.03 rev a) Can anyone help me?

Please tell sSpec of your new Q9650.
