It could be a failed BIOS flash or just corrupt BIOS or a toasted DAC. Have you tried the other outputs from the card?

Generally speaking, you will not be able to mix and match GPU's in a system like this.  They need to be from the same company and from a similar series.

 

You may also want to return the VBIOS to stock, preferably using a backup of the original.
