There should be 2 6 pin connectors you have to plug in, check again that they are both plugged in correctly, if that doesn't work your psu may be too weak.
I have both connectors plugged in to the card. To clarify a few things, which I should have posted in the initial thread:
I have a brand new Rosewill 600w PSU, the Radeon 6950 IS running, fans are spinning, led is on, etc...
My VGA port which runs directly from the motherboard and the integrated graphics (nVidia Geforce 7050) will still work when I plug my monitor into that port, even with the new card plugged in.
My computer DID recognize the new card and installed the new hardware when I first booted my computer after installing the card.
I have found that my motherboard in my crappy et1810-03 eMachines is linked to nVidia in some way, could this be causing compatibility issues with the new catalyst software?
