Pc loses sound

[Nites]

Below are the details of my machine the problem I have is it keeps losing sound. Its got Soundmax installed, I've reinstalled it and uninstalled it so many times but yet it still loses sound! When the pc is 1st booted up I got sound but if I try and say for instance open a program or a webpage it'll go off. I've done all the regular checks that you've posted elsewhere on this forum but to no avail. Updated the driver using Drivermax as well but it still does nothing. I'm at my wits end. Bear with me I'm not a complete novice but this side of things can sometimes throw me!

When you say you updated the sound drivers.
Did you?
Update the chipset first?From SIS?
Go to SIS directly and use their drivers?

I don't see anything on their site for SiS 760, AMD Sorry I been at this for hours now my brains a tad fried!

Ooops my mistake ..apologies SiS7012..tried installing it but i get this ...

[Niclo Iste]

have you tried removing the previous drivers manually and then manually installing the new drivers from their website? I do not mean using their auto-installer but manually choosing the drivers from the device manager.
