Unknown Device named “PCI data acquisition and signal processing controller” in Device Manager

Greetings,

Yesterday, my brother who was running the Windows 8.1 Preview on his Asus S400CA Ultrabook ran into a big NTFS partition corruption problem that made it impossible to recover via the Windows 8.1 refresh utility. Given the situation my brother decided it was best to return to Windows 8, I had to install Windows 8 on his PC using an external DVD drive with a full retail Windows 8 x64 installer that I had previously purchase. The computer never asked me for a product key which I read is normal in Windows 8 PC which now have these embedded into the motherboard. So far a smooth installation, however it got tricky in the part of driver installations. Before deleting the computer I went to the Asus website and did my best to find the drivers specific to my brother's computer and downloaded the essential drivers, chipset, intel graphics, audio, bluetooth, Wireless LAN, LAN, and Asus trackpad and installed them. I used the Device Manager to check out which drivers were installed and which were not. I was able to get most of the drivers correctly installed however, the Device Manager is saying I am missing the "PCI Data Acquisition and Signal Processing Controller" driver. Unfortunately I have going to Asus website to see if I can find the driver however, I am unable to do so at this time.

Check the attached screenshots for a better view...

I also tried using Windows Update to see if it could find the appropriate driver and unfortunately that was a dead end. Due to this I am writing in this forum to see if someone can point me in the right direction when it comes to this missing driver (and the others) shown in the Device Manager.

One last thing that I would like to ask is if I can use a utility like DriverMax to find the missing drivers or should I go and install them manually?

Many thanks in advance for any assistance on this matter.

    I worked on this issue for over an hour.

    I hope this helps save someone some time.

    It wasn't the chipset driver for me.

    It was this:

    Others (8)

    Version  V7.0.0.2023
    Description Intel® Dynamic Platform and Thermal Framework Drive
    File Size 5,88 (MBytes) 2013.05.27  update <br> --- ---
    Download from  Global (DLM)  Global  P2P <br> ---

    You have to go to Windows 8 drivers, not Windows 8.1 drivers to see a lot more available drivers.

    It's buried in the "other" drivers. 

    As soon as I installed this driver. All drivers are now installed and nothing is in yellow.

    Hope it helps.

    Hi Mike,

     

    Thank you for keeping us updated on the status of the issue. Please feel free to reply, in case you need help with Windows in future.

     

     

     

    Okay, 

    ASUS Tech Support according to my brother was a little of a dead end, so I went to do another Google Search and found out the culprit. I was missing the following Drivers from ASUS:

    • Intel® Dynamic Platform and Thermal Framework Driver
    • ASUS Wireless Radio Control (A driver to make you switch Airplane mode(Wireless) On/Off)

    The first driver took care of the PCI Data Acquisition and Signal Processing Controller and all but one of the Unknown Devices. Finally the second one took care of the last Unknown Device in the Device Manager.

    I would have never thought that ASUS would use such a strange name for their driver because those names are extremely misleading.

    Other than that, I can finally say for certain that my brother's computer is back in business, and I can call this Windows 8 restore process complete.

    Thanks for all the assistance Zaki J, I greatly appreciate all the guidance through this process!
