No Beeps, Black Screen following failed Graphics Card Install

System:
Intel E8600
2x2gb Corsair 1333
Xonar D2 audio card
[1st video] Asus 4870 pci-e
[2nd video] Sapphire 7000 pci

After flashing my 4870 (the only card installed at first) with the wrong bios, I was unable to get the computer to boot up. Although the lights on the MB turned on and the CPU fan spun, I was not able to get the computer to show anything other than a black screen.

To flash the graphics card back to its original BIOS, I installed a second graphics card in the first pci slot (and removed the 4870 so that I could configure the bios correctly). The computer booted and loaded the express gate screen. I ignored a warning that suggested Express Gate was not installed fully (an issue that I had not encountered before) and loaded up Windows (XP pro). The OS loaded, started to install the new set of graphics drivers and then the screen went black again.

Since this point, the motherboard lights are still green, but I hear no beeps (although I had disabled the onboard audio in the BIOS previously) and I the screen is black. I’ve tried a number of times to reset the cmos (removed battery, changed jumper positions, started with only one stick fo the RAM), but to no avail.

Anyone have any suggestions for approaches to try and get the item jumpstarted?
