Wow so I just received my new 6870 in the mail today and guess what... it doesn't work. Well, here's what I did so far. I uninstalled all nvidia graphics drivers, which I used for my 9600 gso. Rebooted to complete installation. Disabled onboard video drivers. Shut off computer. Installed 6870 into motherboard. Booted up. Now I don't get any video from the card outputs itself, so I used my onboard video output to log into windows 7. I tried installing the CCC, but the installation failed or something like that. I check the device manager, and there isn't any sign of the 6870 showing up. Now I'm a little scared, and not sure what to do. The 6870 appears to be powered, cause my computer is x10 louder with that damn fan. Its just that it won't be recognized by device manager and the drivers won't work. Thanks guys. Edit: When I installed the 6870 I had to move the hard drive and cd sata cables from the first and second port to the third and forth ports. Whenever I boot, my POST says your system last boot fail or POST interrupted. Please enter setup to load default and reboot again. I press f1 to bypass this. Also, when I go into system, for some reason it only detects 3.87 GB of RAM... I have 64 bit windows 7 <-- it only started happening since the new graphics card was installed. Reinstalled Windows 7... same damn problem. Also, I'm starting to think that the graphics card is defective, as even the bios cannot recognize the card on boot. And I believe that is the reason for the POST failing.
