dell optiplex 745 not detecting second monitor after installing windows 7 ultimate

[Vix_2016]

After upgrading to Windows 7 Ultimate from XP os, my mini tower Dell Optiplex 745 lost dual monitor setup. For some reason, it keeps disabling one of the graphic cards. Either I use the external card or the integrated one. The external graphic card is recognized as a generic nvidia geforce 400x with a VGA port. The integrated graphic card has what look to be two VGA ports, a male and a female. Is there a driver out there for Windows 7 Ultimate to enable both cards to run like they did when I had the pre-installed XP os?

After doing the Windows 7 install, did you install all the drivers for the motherboard as well as the graphics cards?

I went to the manufacturer site and downloaded the drivers for the motherboard. I tried looking for the drivers for the graphics card but can only find the vista version, not windows 7 - 64 bit since it's unavailable.

You should be able to get GeForce 400 drivers from Nvidia itself, nvidia.com
From there you will get the latest drivers and for your OS as well.

I tried that. Nvidia auto check utility said their drivers are incompatible with my hardware >_<

Don't use the auto detect then.

It's not working. I still get the yellow bang in device manager "Standard VGA Graphics Adapter" and still the second monitor is not detected.

Be very interested to see this card.

Here's what the graphic cards look like according to my system. But one is disabled.... due to missing driver(s)...? I've done the bios setup back and forth, switching my monitors around. They both work separately, but won't do like they did before which was dual monitor enable simultaneously.

According to that screen shot the other card is a VERY old GeForce 2.
I'm not sure how that would be possible since the chipset on your motherboard is a Q963/965 which only supports PCi-Express slots, not AGP, as far as I can tell.
Unless the motherboard manufacturer put an AGP slot on that board.
Anyhow, you are looking for drivers for the GeForce 2 card then from the Nvidia site.

 

[Vix_2016]

okay, will try that, but I did try to re-install the drivers from my XP back up files, which didn't work either -_-

 

[Petrossa]

Never mind.
You're not gonna get any joy from the Nvidia site. I just checked.

UPDATE:
Disregard anything regarding that Nvidia card.
I read your original post again, and it seems that you did an UPGRADE from XP to Windows 7.
I suspect that you might have had that hard drive with XP in another, older system before you put it into this current system and that this old system had the mentioned Nvidia card in it.
Am I correct?

 

[Vix_2016]

Yes

 

[Petrossa]

I'm afraid you are stuck with 1 x VGA connection only. The other one is a COM port.
If you are wanting 2 screens, you will have to purchase a newer graphics card.
If you're not into gaming, then a cheap card with a Nvidia G210 on it will do nicely.

Okay. Thanks for your help though

My pleasure.
Sorry it took such a long time, but the penny eventually dropped.
