Laptop OS upgraded, now no sound!

By brifd1 ·
I have an older Gateway laptop (7330 GZ) that I upgraded from Windows XP to Windows 7 (32-bit Home Premium). Ever since, I have no sound in the laptop, even if I plug in headphones. I tried the Control Panel, updating drivers, downloading I think it?s called AC-97 for the sound, but still nothing. Recently, I tried connecting the PC club to a new LCD TV, which for some reason caused the TV to keep turning off without explanation, but when on there was neither picture nor sound despite my pressing the correct function key + number key combination to change to projection. Okay, there?s more than 1 issue here, but the one re: the sound is the one that?s most important for me to find out.

Did you run the MS suitability tool to see if this "older Gateway laptop" is up to W7? Maybe it isn't.

RealTek's driver update utility? It's supposed to be able to id your hardware and supply the latest driver for it. Never used it myself.
Gateway did some strange things with hardware and there may not be a Windows 7 driver for yours.
