Sound, video and game controller missing - Now what?

Hello and thank you already if you are reading this.

My problem is that:

-I cannot find Sound, video and game controller in device manager and have no sound.

Soundcard: Realtek ALC883

Here Is what I have done:
-Installed w7 64 today, C all clean.
-Downloaded and installed realtek drivers for my motherboard MSI K9VGM-V from here:
http://www.msi.com/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=260
MSI says they are w7 compatible. The driver installs normally.

What I get:
-Typical red cross on speakers in systemtray
- No sound, video and game controller in device manager.

What I attempted:
-Tried to disable 'azalian' (or what it was called) in BIOS which is supposedly the 'sound control'. No change in w7, -set to auto again afterwards. CMOS was flashed recently.
-Tried to install various drivers among these: r2.48 HD audio w7 64 from realtek.
-Did of course try to search for PnP in device manager many times.

What I know:
The onboard sound card worked fine before when running on a vista64 install. Everything else on the computer is running smoothly after install.

Notes:
When uninstalling prior to attempting installation of alternative drivers, I receive the message: "unable to remove files" or similar. I have searched registry for 'realtek' but only find 'history files' from winrar. ...or something like that.

What I don't know: :)
On the MSI driver page there is listed a '4in1' driver? Is this something I need? I don't know what it is and it only has XP64 support so I did not install it.

-Again, thanks for reading and I really appreciate all input, also suggestions for alternative drivers, but I think the missing 'SVaG' controller is the issue (?)

Cheers, Kokos.

I have tried installing 'Vista_Win7_R248_x64.exe'. That is the newest on realtek.com.tw
No changes, sound, video and game controller still missing. Ideally I would get a proper soundcard, yes. But now I just wanna make this one work.

Is there no one who can help me?

kokosbolleit could be due to incomplete Via chipset drivers included with Windows 7, and that is why nothing is showing in Device Manager with regards to audio. The one thing I found on the Via forums with regards to the chipset on your motherboard (K8M890) is that there are no Windows 7 drivers other than whatever comes with Windows itself.

One thing you can try is to go here,

VIA Drivers Download - VIA Technologies, Inc.

work your way through the drop down boxes till you get to the Vista 64 bit "VIA Hyperion Pro Driver Package". You may have to install it in Compatibility Mode,

Compatibility Mode

If they install then have a look in Device Manager and see if there is anything showing for audio, and if there is then try installing the Realtek driver.

Thanks for suggestion and links. The hyperion 4in1 drivers installed succesfully. There were some issue with the pci network card trying to reinstall itself on each restart that now seems to be gone. :)

However, the SVaG controller did not resurface, so problems remains...

Reinstalled the R2.48 realtek drivers too.

BTW, when I click the sound icon in system tray it starts searching for hardware then I get the message "Problems found : hardware change may not have been detected." Is this a common message ?
