Audio Device Driver Required - Windows 7 64-Bit - Asus P5VD2-MX Motherboard - CPU: Socket 775 - Audio device "Unknown"

Ok, as the title says, i need the correct Windows7 64-Bit driver (FYI... Asus DO NOT have any Win7 Drivers for my board eccept for Bios Flashers)


Previouse: New computer (To me its new, it was my brothers) Worked fine for him but came with all drivers pre-installed (He also used Win7 64-Bit)


I formatted the drive and re-installed win7 64-Bit. It showed the device as working including in the device manager, however, no matter what i did i got no sound. I tried to find drivers online and found one saying it was the win7 64-bit driver, it installed fine but had to reboot to finish the install, o nreboot it gave an error as i logged back in (Cant remember what it was now) and now there is no device showing up at all anywhere not even in Device Manager and not even showing "Unknown Device"


I have been to Asus website and tried the Win vista 64-Bit Audio driver for my motherboard and it says it is not compatible.


Note: I have been through the entire FAQ on the Asus website and they have no useful information what so ever, as with the forums.

Note: Have also checked in Playback Devies panel and shown Disabled Hardware... still nothing

I have tried using SIS software "Sandra-Lite" and it cannot detect any audio devices


If this is a bios version problem and i have to flash it, please let me know and if possible provide a link to the correct flasher... ive not flashed a bios since 1998... Dont want to screw it up XD

Any help would be much appreciated


Thanks in advance
