Each motherboard (or motherboard series) has its own driver that must be installed, so I would advise going to the manufacturer's website to find the appropriate driver. You will need to know the model of computer (or in the case of a custom-built computer, the brand and model of motherboard) so that you make sure to find the right software for your machine. If you would like for me to assist you in this endeavor, drop me a line and I will be glad to help.
sound driver for windows 7
If Windows 7 could not find the right driver you will have to install manually. And it would be as you said Marvell 61XX driver.
You need to install a sound card driver which you can find on the motherboard/computer manufacture website.
Just found it. Go to control panel --> System and Maintenance --> Devices Manager --> Display Adapters and right click your graphics card and click properties. Click the driver tab, and next to "Driver Version" will tell you what version you have.
There is no such thing as a "motherboard driver." Motherboards are composed of several components, each of which needs its own driver. The drivers needed for the components can usually be downloaded from the manufacturer's site.
Read the owner's manual for your motherboard.
nvidia geforce 8200 is a motherboard, not a sound card. It has a Realtek HDA (Azalia) soundcard integrated.
The manual of the motherboard is provided with the motherboard itself while purchasing it.
You can find the motherboard model no. on the motherboard itself. It is always written on the motherboard. If you want to find it in windows, then go to Start Menu- Click Run- Type DXDIAG and Press Enter. A DirectX diagnostic tool window opens, here you can find every detail about your computer including motherboard model no. Hope it helps...
It should say on the processor tray on the actual motherboard itself.
