I downloaded and installed the graphics card in windows from the manufacturer (alienware.com), it went black and when I restarted an explanation point beside the VGA device revealed that it didn't take.
I booted to safe mode, uninstalled and reinstalled, it worked, and I booted into safe mode again. The display adapter was showing all nicely.
I booted to normal mode, and it just went black right away again.
Where do I go from here? Any suggestions or troubleshooting tips would be greatly appreciated.
