Same thing happened to me when I built my computer 2 years ago with a 550 gtx card. (since upgraded that) As far as I can remember, I just went to the Mobo site, downloaded everything the driver section had (the appropriate version ie: 64bit for me, 32bit for some) and installed away. Once I reset, the vid card drivers were next, restarted, and everything seemed to work fine. This included a CMOS update too to the latest version. Make sure you find out the proper way to update your CMOS, follow the instructions on the site.
