But it needs to have two video output connectors. Most modern VGA's come with a normal VGA output, and a DVI output, which can be converted to normal VGA signal using a DVI to VGA converter.
I think that there's no way to enable your onboard VGA, if you have another video card.
But with your current, non-integrated card, you can display an image to two monitors, of course, if your card has two video outputs (normally, 1 blue, and 1 white, or 2 white ones).
For example, you have a card with 1 blue "Dsub", and 1 white "DVI" connectors. Your normal CRT connects to the Dsub connector, and the second monitor, connects to the DVI connector, using a DVI to VGA converter
If it is possible to enable your onboard graphics to reverse the automatic disabling, you will have to try to do so in your BIOS. With at least some motherboards with onboard graphics, I understand you can run both but I don't know if that applies to motherboards that automatically disable onboard. If the option is not greyed out in the BIOS, you can try it and see.
It depends on your motherboard. It may be accesed by pressing the delete key, escape key, or F1 key while your system is booting (during the POST usually).
Can you give us your motherboard model and make, so we can help you better?
I ran Everest and my motherboard is Asus A7V8X-LA (Kelut) (3 PCI, 1 AGP, 2 DDR DIMM, Audio, Video, LAN, IEEE-1394). i also filled out my computer in my profile
you are correct about how my video card looks like. unfortunely my video card did not come with a DVI-VGA adapter. but it seems like it is pretty cheap to buy.
And as a last thing i'd like to thank all who helped me.
