Sound Card Driver just won't work

Sorry to bother you guys, but I really need some help.

I've recently formatted and installed Windows 7 Ultimate (64 bit), after doing so all the drivers par from 2 are functioning properly.

In device manager it specifies that two devices are not working properly, a unkown device and High Definition Audio.

My motherboard:

I've downloaded the latest drivers from realtek (says windows 7 (64bit) compatible), no luck. I tried to use the drivers from the disk supplied by the company when I originally bought the computer, disk cannot load. I've tried downloading sound drivers from the motherboard's website, no luck.

What should I do?

If you cant get the Windows 7 drivers to work try using the Vista ones... they work just as well.

(I had some problems with that today)First make sure,go to safe mode and from uninstall programs,uninstall the realtek driver.
then you will have to reboot,when you do it boot again in safe mode (just make sure that the realtek folder isn't listed in your program files folder.If its there it should have some useless files.delete the realtek folder.Start the Realtek installation.Then reboot.It worked for me.

What would you recommend? I haven't yet checked but I'm pretty sure my friends computer is using the PCI Express x16 slot for his graphics card, so the soundcard would have to be PCI Express x1.

I'm also thinking of purchasing one for myself, my motherboard:

Which sound card would be suitable for these two boards and be within a price range £20-£40 ($35 - $58)
Huge thanks for all the help

May be a bit of a stupid question but; When you use a USB headphone, does it use the soundcard or not? As a alternative to fixing the problem may be just to buy a USB Headset and use that instead[/quotemsg]

Don't forget to disable the other audio device from the bios,I have to disable AC97 to use HD realtek audio.
Also check,On realtek HD audio manager click on connector settings(the yellow folder) and check the 'Disable front panel jack detection' box. i hope that helps

I know,i had exactely the same thing! I just clicked on start,search 'Realtek HD audio manager', and then once it finds it run it,uncheck and check back again the 'Display icon in notification area' box.it should work.If you have followed my steps, it should work.
