Dell computer problem

[copelandtml]

Hi there,
I have a Dell Optiplex 745. When I turn on the computer I get this message:

Attention: unsupported video configuration detected action is required
This computer has an add-in graphics card, but the monitor cable is plugged into the integrated video connector.
To attach the monitor cable to the add-in graphics card:
1 shut down the computer
2 Plug the monitor cable into the add-in graphics card connector this may require a video adapter or video adapter cable (provided with system)
3 turn on the computer

I can't see anywhere else to plug the cable in other than the blue one at the back. Do I need to buy some sort of adapter cable? Someone told me I need a DVI to VGA cable, is this right, or is there an alternative?

Thanks,

Can you take a picture of the back of your PC and upload it to Imageshack or Photobucket for us to see?

The white connection underneath where the speakers plug in is a DVI Connection. That is why you are getting the error you are. From the sound of it the person that told you about hte VGA to DVI converter is right. You will need that converter piece to attach your monitor to the DVI connection and stop this error.
