No Sound device on HP Pavilion dv9700 [ Edited ]

[Skylined]

Hello, I am checking out a notebook computer for a friend...

He sent to a technician because his hard drive had crashed, don't know why he didn't send it to me in the first place.

The tech replaced it and installed Windows 7 32bit, but there was no sound, no webcam and the DVD drive was not visible in the OS. I tried to install the 32bit audio vista drivers from HP's website (tried both Conexant and Realtek, and the older ones also) but it kept giving me the error: "Driver installation failed: Could not find the device for this driver"

Since the computer had 4GB of memory, I reinstalled it with Windows Vista Ultimate SP2 64bit.
The reason for Vista is because I know I had experiences in the past where these machines are sensitive when it comes to drivers, especially the audio.

But I kept getting the same error, you do not even see the devices in the device manager.
I also installed the Microsoft UAA...

I still cannot see the DVD drive (you can eject the drive manually using the hardware button)

Also the webcam is also not recognized...

I even tried a hard reset (removed battery, held the power button for 30 secs.)

Now the the last tech. who checked the machine seemed to have opened it up, for what reason I do not know because the hard disks are accessibly in the back through a small panel.

Anyone has any ideas?

Here is the system details:
HP Pavilion dv9700
Model: dv9925nr
P/N: FE695UA#ABA

Hello

If it possible can you share hardware id for sound card?

you can find hardware id in device manager.

you should find your audio card then right click on sound card then properties then details finally chose hardware id.ü,

There is no sound device or unrecognized devices in the device manager...

did you check hardware in bios? if all setting OK, i guess you have hardware problem.

I did a hard reset, I also upgraded to the lastest BIOS available from HP. and also reset it to defaults and still the same problems.

There are no options in the BIOS for sound/webcam...

i guess you have hardware problem. you can change your motherboard or you can buy external audio device

I had a feeling, this machine is really a piece of crap, I have Acers, Sonys and even Gateways that last longer than HPs

Thanks anyway...
