Windows 7: "No Audio Output Device Is Installed"

This has probably been posted here before, but I could not find any threads on this issue. I re installed Windows 7, and once I finished, I logged on, and tried to watch a video online, and realized there was no audio. I looked at the speaker to see if it was turned on, and there was of course a red x on it, and the message "No Audio Output Device Is Installed" once I dragged the mouse over it.

Any idea on how I can fix this?

So I opened the Device Manager, and saw that my Multimedia Audio Controller had a yellow mark next to it. I right clicked and clicked "update driver software" and this message came up.

" Windows could not find Driver Software for your device."

Anything else I should attempt?

I'm not sure as to what Sound Card I'm running. How can I find out?

EDIT: Figured it out, it's an onboard soundcard

Thanks
