Audio driver for Compaq NX7400 in Windows 7

[jingqwerty]

My OS is Windows 7 Professional. The computer is Compaq Nx7400. Can anyone tell me where I can get a compatible audio driver for this laptop? I tried installing the one available for Windows Vista but I think it's not compatible since the computer always turns to blue screen (with dumping physical memory, etc.) so I uninstalled that driver and up to now, my audio device is not working.

Another problem is that this computer go to this blue screen thing from time to time and I'm worried that eventually this might not entirely work anymore. How can I solve this? Thanks!

Hi,

Go to Control Panel -> Devices Manager

Click with right button of Your mouse on each yellow sign and choose properties. Then go to bottom details and paste here Hardware Ids. This way we will know what it is.

Below You've got example how to do it:

It seems that you've got installed still some kind of driver for audio....

There are now listed 2 other devices first is bluetooth and second HP Quick Lunch Button.

For Bluetooth try driver for Win7 provided by Broadcom here (I'm not sure then this will work. Please remember then Win7 haven't been released official yet and there isn't all driver for devices from HP)

HP Quick Lunch Buttons here

When You will uninstall this driver for audio there will be new hardware id to copy. When You will post me it I will try to find solution on this last problem.
