No sound in my newly installed Windows 7beta

Hello friends,
I have recently began to use windows 7 on my computer which has the following configuration

Intel pentium D,1.8 GHZ
1 GB Ram
80 Gb Harddisk.

However,After installing Win 7 Beta,I have not been able to listen to and Audio Files.

I tried to install the drivers,The vendors gave me,But they were not compatiable with Windows 7.

I know that its a frequently asked problem,But i expect personalized support ..Pls help me to slove this problem

Which sound card do you have? That's the bit of info we need

Its a realtek soundcard and i dont know the exact model or version details(How to find it).

Try running "dxdiag" from the run menu and see if any more information pops up under the sound tab.

when i typed "dxdiag", A window opened with a title "DirectX Diagonstic Tool".

I selected the "Sound" Tab

There was no information under the titles Devices,Drivers,All the fields were empty.

In the bottom of the region,under the title "notes",There was this msg:

"No sound card was found. If one is expected, you should install a sound driver provided by the hardware manufacturer."

Is it an onboard sound card? If you know the model number of the motherboard I can find out from that.

Yes,I think its an onboard sound card.But i dont how to find the model name,,How to find it?

The Everest trial might tell you your motherboard model (and perhaps your sound card):

If not, when you start up your PC it should come up with a make and model. If it's an off the shelf PC like a Dell or HP, it would have the model written on the case and I can look it up from that.

That was a good piece of software man. it gave me the following information
