This drivers don't work. I can't install the sound, I have installed first the Microsoft Universal Audio Architecture (UAA) Bus Driver, but the sound driver is not good. The wireless is the same, not good. The others I haven't tried. what can I do???

i installed the linked xp drivers for my downgraded C751nr, however while the sound card now works i have no volume controll, is this something that can be easily fixed or should i just run no sound?

Are rest of these drivers (other than audio) working for you?
Please make sure that you have Service Pack 2 installed for Windows XP

I am having the same problem with the audio driver, the first installs correctly at which point windows recognizes an audio device and prompts for driver installation. I cancel and attempt the second part but it errors with the message: Driver Installation Failed: Could not find MEDIA device for this driver. Thanks for any help

The driver must be different for you.
Normally drivers are common for all C700 series laptops. Kindly try drivers for the same device from other laptop entries in our website.
Let us know what happens
