Hi:

 

Yes, you need a different driver for that device.

 

I have zipped up and attached the driver you need below.

 

Do the same steps as you did with the other one I attached yesterday, and you should be good to go.

Hi:

 

You need this driver for the PCI E/D Controller that I have zipped up and attached below...You will have to manually install the driver.

 

To manually install the driver...

 

Download and unzip the file to its folder.

 

Do not do anything with the files in the folder.

 

Go to the device manager and click on the PCI E/D Controller needing the driver.

 

Click on the driver tab.  Click on Update Driver.

 

Select the Browse my computer for driver software option and browse to the driver folder you unzipped.

 

Make sure the Include Subfolders box is checked, and the driver should install.

 

Then restart the PC.

 

Unknown Devices...

 

Try these...

 

This package provides the driver for the HP Wireless Button on supported models running a supported operating system. HP Wireless Button allows the physical (hardware) wireless radio button on the system to enable and disable the wireless connection on the system.

Receives notifications from the integrated accelerometer and automatically parks the hard drive to reduce the risk of damage if the PC is accidentally dropped.

Thank you so much for the reply! :generic: PCI Encryption/Decription Controller is now recognized and it is solved! I installed this first driver for Wirelles button and then tried to install other driver for 3D accelerator, but during instalation it says error 1722. The unknown device with yellow exclamation still remains in device manager...

You're very welcome.

 

That might not be the driver you need then.

 

Please post the hardware ID for the unknown device, so I can figure out what driver it needs.

 

To find the hardware ID, go to the device manager and click on the unknown device.

 

Then click on the Details tab at the top of the unknown device window.

 

Now you will see a Property drop down list, and it will be set to Device Description.

 

Drop down on that list, and select the 3rd item (Hardware ID's).

 

Post the top string of characters that you see in the window.
