You've got to disable the onboard video in the bios. Otherwise it's the only video you can use. The option to disable it should be in an advanced menu. It's usually farily easy to find. If you get really stuck and can't find it read the manual. It is in there somewheres, and until you turn it off you can't use a PCI-Express video card.

As for getting windows to work again, you'd have to boot into safe mode and then reenable your video card. You should never disable your video card from device manager. If safe mode doesn't work then, the only way to fix it is to get the second video card installed properly, or reinstall the system.

 

What MB do you have?

 

Have you remembered to plug your monitor into the new gfx card?
