Question : Error installing Radeon 7k into HP DC5700

Trying to install a new PCI Radeon / Visiontek into a HP DC5700.  When I insert card, system will not boot up. I get the error beeps from the tower indicating display errors.  

The only thing I see in the BIOS option is to disable the IRQ for the intel display adapter which I have tried to no avail.  WIth the new card installed I can not even get to the bios options.

In that case I would guess it's either a bad adapter or it's just not compatible with your computer.

Can you try it in another computer to test?
