Dell's bios only allows for "Auto" or "On" for the onboard video adapter.
Hmmm ... try this.
Boot to Safe Mode
- Turn PC on.
- As soon
as the Dell logo screen goes away press and hold the F8 key.
- You should be presented with the "Boot Options" menu.
- Use the arrow keys to highlight "Safe Mode".
- Press Enter.
Disable the onboard Intel Extreme Graphics
- Start button --> Right-click on "My Computer" --> Left-click on "Properties".
- Click the "Hardware" tab.
- Click the "Device Manager" button.
- Locate the "Intel Extreme Graphics" adapter.
- Right-click and choose "Disable".
* While you're in there be sure to right-click and "Uninstall" ANY other video adapters present.
Get rid of ALL video drivers
- Go to your "Control Panel".
- Choose "Add/Remove Programs".
- Remove the Intel Extreme Graphics drivers, if they are present.
- Remove Any/All Nvidia graphics drivers.
Reboot your PC.
Upon reboot you should be prompted by the "New Hardware Wizard" ... Cancel it!
It should use a Standard VGA adapter and you will be in a reduced graphics mode, no worries.
Turn off ANY antivirus, spyware, security-related programs.
Run the driver installation CD that came with the New card.
Once finished ... Reboot your PC.
If that doesn't work, or you if have additional questions, please be sure to let us know!
Hope this helps.
