Computer Type: Dell Optiplex 780

Opperation system: Windows 7 Pro

 

 

On boot I'm getting the following message.

Attention: Unsupported Video Configuration Detected
Action is Required
The 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:Shut down the computer.Plug the monitor cable into the add-in graphics card connector.
This may require a video adapter or video adapter cable.
(provided with the system)Turn on the computer.This message should not appear after completing these steps.
For more information or help, please refer to the system documentation.
System Halted!

Now this computer is quite a few years old, so it's using DVI as a video output.

As you can see, its using DVI as the monitor input.

At this time I can buy an adapter that is DVI to VGA, but I'd prefer changing this in BIOS.

However.... I can't get into BIOS

 

 

 

I'm using a USB dongle for Logitec Keyboard and mouse 

 

 

On boot, I get the Attention: Unsupported Video Configuration Detected message, and I cannot get past it.

Here's what I have tried

 

Smashing F12. 

 

While Pushing F12 should load BIOS Pushing it quickly while the PC tries to boot lets out beeps (letting me know the keyboard is responding yay no USB not loading before BIOS issue) but it dies out and hits the error message again.

 

Removing Cmos Battery.

Removing the battery doesn't allow me to move forward, as it did for one chap with a simalar issue.

 

Sooo I'm here

any tips Girls/Guys? :D

Power the system down.  Reset the video connections to what they were originally, using the onboard connectors for the monitor.  Then try to boot to BIOS.

 

If the system is not using the correct video connector/GPU...there won't be any video on the monitor screen.

I agree with Louis :)  .  

 

If the monitor has a VGA option, use a VGA cable and try the onboard video card.   VGA cables are cheap and plentiful if you don't already have one.   Hopefully your monitor accepts VGA :)  .

Hmm okay, I may need some help with that.

The Dell™ OptiPlex™ 780 Service Manual States on page 5 this computer supports for Video 

 

Integrated

 

Intel graphics media accelerator X4500 up to 256 MB shared video memory (total system memory greater than 512 MB)

 

Discrete

 

PCI Express x16 slot supports either a PCI Express card or a DVI add-on card (for dual-monitor support)

Looking into it, it seems this computer has a  DVI add-on card installed. 

 

(I'm not certain if that means it comes factory with DVI or that's just an option that exists on my unit from the prior owner?)

so when you say 

 

 

Reset the video connections to what they were originally, using the onboard connectors for the monitor. 

 

Are you indicating I should pull out the DVI card?

if possible I'd prefer to keep it in as DVI can be preferable to VGA connection. (for HDMI that is)

Awaiting response before I start yanking out parts :D

I would remove the DVI Card.  Optiplex native support is the Intel integrated video, not any other.  The support for the add-on card...is just an option that the system has.  Forget the optional, go with the native integrated video/graphics.

Here's what I'm looking at

I get the error message when booting up with a VGA cable connected to the Blue spot. 

 

I think the computer is wanting a cable plugged into the bottom row, where the Add-on DVI plug is.

After removing the DVI Card the computer boots!

Thanks for all your help, it makes sense now why it would not start up.

I would just like to point out that it is F2 to enter BIOS setup not F12. F12 is to select Boot Sequence.

Although the issue is fixed for this computer, I wanted to come back and thank you for this bit of advice.
