That is probably an ECS motherboard but I can't be absolutely certain as I didn't see your exact specified model # on their site. I bet there is another # somewhere on the motherboard that will allow you to determine exact model #. To that end I recommend downloading and installing SciSoft Sandra ( newest version ) from here
This program should help you determine exact manufacturer and model #, and if it is an ECS motherboard as I suspect that it may be, then visit this site to find the motherboard on manufacturer website and download the drivers there.
In the long run you will be happy you used drivers from a manufacturers website vice the many so-called driver sites on the web. A lot less hassle.
