First of all, my main goal is to connect 3 external displays to my desktop, one DVI and two VGA. To do this I’ll need to use my PCI Express video card and the graphics on my motherboard because my video card has one DVI and one VGA. Therefore I’ll need to use the extra VGA in my motherboard. But my motherboard graphics don’t work unless I unplug my video card and I can’t see why it does this. So as of now here is what’s happening; I got two external displays working, the DVI and one VGA, Both on my video card, a VisionTek Radeon HD 5450. When I try to plug the third monitor into my motherboard and click detect, nothing happens. My motherboard is an ASRock N68C-GS FX, the graphics in this motherboard is an NVidia GeForce 7025. It does not show in Device Manager though the driver/NVidia software seems to be working fine. I’m not really sure what I can do at the moment (other than buy a video card with more VGA/DVI ports…). Thanks for your time, and I hope there is some kind of solution to this.

Another Problem you could really help me with!
As you may have read above, I have a VisionTek Radeon HD 5450 video card (I know, it sucks). This doesn’t happen too often, but sometimes when I power on my desktop the video card just stops working and only the motherboard graphics is working. Even when I restart the computer this will still happen. The only way to fix this is to unplug the video card from its PCI Express slot, start the computer, turn it off, and then plug the video card back into the PCI Express slot. There probably are not really any easy solutions to this, though it would be really helpful to know if this problem is coming from my video card or motherboard.

Hi :) 

You CANNOT run both onboard video and a card.... it just will NOT work...

Get a better graphics card with 3 outputs....
.......................................................

Your second problem is caused by having the onboard plugged in at boot...unplug it...problem solved...

All the best Brett :)
