Thanks everyone for the input.
I upgrade the BIOS on the Asus A7V MB and finally the system boots up. 
 I am receiving errors when initializing the 2nd PVR-250MCE tuner card. 
 Here is the output from the messages file...

You notice the message about failing to register IRQ -16?  What can I do 
to get this adapter recognized properly?

Thanks again for the help!
