Card not found in Device Manager

Is this one of the new 9800GT's that don't require external power? If so then maybe your mobo is not putting out enough power through the PCI-e slot.

Sure is. I'm digging through my BIOS settings looking for a voltage option...any ideas where it might be?

That won't keep the card from being picked up by Windows. I'd follow my advice if I was you. I have been through this procedure many times at the EVGA forum.

I would uninstall the drivers "if they installed" then shut down and remove the card. Reboot and then shut down again and reinstall the card into the PCI-e slot making sure that it's seated correctly, sometimes it helps to clean the contacts. Restart and see if Windows see's the card, it should install the VGA drivers if it see's the card. Repeat the procedure until the card is recognized.

So I uninstalled all drivers and rebooted. Then shutdown, removed the card, and restarted. Shutdown, installed card, not found. Shutdown, removed card, reboot...shutdown, install card, reboot, not found. Did this about ten cycles with no luck.

Among all this, Windows 7 like to "help" by auto-installing the drivers for the onboard device. I dual booted XP and tried on that too with no luck.

I think tomorrow I'm gonna go get another brand of the same card, and see if it will recognize that one, and maybe this on in the SLI slot...who knows. I'm getting very frustrated at this point.

Did you ever find a solution? I'm having the same problem and nothing has worked for me.

Nope. Periodically get it to SLI for a couple days, then disappears again. Ended up buying an ASUS card, and it has no problems. I think that the PCY drivers are not working well with W7.

Heres a manual I MADE for this kind of problem , i had the same problem so
i wanna share this manual , its a powerpoint with solutions and programs
