Answer:
Did you disable onboard graphics surrounded by the BIOS?
Did you uninstall any old symbolic drivers?
You install the drivers first before putting the symbolic card into the system. After putting the video card into the PCI/AGP/PCI-E slot, boot up your computer and it should detect automatically.
Try updating your motherboards BIOS.

Also, try updating the chipset drivers.

Then reinstall the drivers for your video card, being sure to use the hottest ones (also found at link above.)
Try only just using this first, you probably didn't remove the old driver first, previously you installed the new driver: http://www.softpedia.com/get/tweak/unins... Driver Cleaner is the best, and most recognized and widely-used driver removal tool on the planet. I've been using it for a few years very soon, and it's great.

If that doesn't solve your problem, then response to nVidia's world! They're known for unfolding the world that every driver they release works with adjectives of their video cards. Like most advertising, it's total BS. While the driver will almost other load, if used near an older card, even one that's with the sole purpose two generations weak like yours, you'll seize crashes.

I own a PCI-E 6600 that would game lately fine with the most recent driver, about 3 months ago, but would crash when I tried to play ANY video surrounded by full screen. It would play those same video just fine, as long as I didn't try to play them within full screen. But, as soon as I go back in the order of 6 or 8 months on the driver, it was unfaultable. That's quite mundane for nVidia, unfortunately.
You can plug it rear on the onboard and try to disable the onboard. But make sure that the drivers are instiled on the avga card.
