Never heard of ConRoe MB. The 865G chipset is well before Vista release. Kinda doubt Vista/Windows 7 onboard audio drivers are available. If you know the exact onboard audio chipset you might find drivers doing an online search. But if Windows 7 doesn't have a driver for the onboard sound, the sound chip may be obscure as far as any OS after XP.
I use a cheap sound card like this on a Vista 64 system I have. I would think the Vista 64 drivers work on Win 7, but not sure.
this is the pop when i try ti install the C-Media AC97 driver nothing happen when i click "ok" .. maybe i should buy a new cheap sound card like "Intex CMI8738 6 Channel" and i saw a driver for Windows 7 on C-Media website "CMI8738 Windows 7 RC Build7100" but i don't know if well work (I'm so noob on sound cards) or what sound card should i get for an old motherboard with Windows 7 64-bit?
Well, just use the new C-media drivers for 64-bit Windows7; they're only a week or so old though...
Really, any C-media chipset will work with their driver install, so you should be good on that front.
FOR those who have a sound problem in Windows 7!!
Try to download a program Device Doctor at http://www.devicedoctor.com/
