Driver problem

I think that is a Gigabyte brand motherboard
GA-945GM-DS2 (rev. 2.0)

If it is then this should be the web link for your drivers
The 1 at top is for audio Choose which Operating System you have and download which fits your pc , you failed to tell us what Operating system you have .
I would book mark the page and download all the other ones you might need also ,while there

If your numbers on MotherBoard doesn't match just look under "Driver" left side 2nd from top and find a better match for your motherboard
Best of Luck
I hope this will fixya friend
