Trouble with audio on desktop computer

[jigsaw52]

I've been searching around the web for a solution to fix this computer. There's a red X on the volume speakers and says, "No Audio Output Device is installed." It's a Gateway computer that was purchased May of 2007. It came with Windows Vista, but I installed Windows 7 Home Premium. I went to the Gateway website to search for the audio drivers and none of them seem to work, or the files come out to be zip folders.

or the files come out to be zip folders.

A zip file should have what you want if you uncompress it, using winzip or winrar or 7zip or another similar program. Install one of those, and open the compressed file/s you downloaded and you will probably find the proper files.
