    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

    That HP Pavilion dv9925nr laptop came with Windows Vista Home Premium(64-bit) pre-installed.

    The hard drive has been replaced and it's had Windows 7(32-bit) installed and then Windows Vista Ultimate(64-bit) installed, so it obviously no longer has the built-in recovery partition that came in it.

    The recovery disc kit is dated June 2008, so I doubt if HP still has it available for purchase.

    It is available for purchase here for $27.00 plus shipping.

    I do not think I would go in that direction, why would I want to get back the recovery CDs and spend more money on something that doesn't make sense, why am I not seeing the devices in Device manager, I more believe this to be a hardware problem...

    I was just giving you that option if you needed or wanted it.

    And I agree it's probably a hardware issue caused from the technician mucking around inside the case.
