Hi: This time, your luck has probably run out. While I was able to help you get everything to work on W7 which was not supported in your notebook the last time, I think W8 is not going to work. In any event, nothing ventured, nothing gained, so let's give it a try.

First, download and run the Vista graphics driver. Close out of any errors you may receive. Go to the device manager and click on the display adapters section to show the Microsoft Basic Display adapter. Click on that, and then click on the driver tab.

Download the latest HP (Hewlett Packard) Compaq 8400 nw8440 device drivers (Official and Certified). HP (Hewlett Packard) Compaq 8400 nw8440 drivers updated daily. Free drivers for HP Compaq nw8440 for Windows Vista 64-bit. Found 13 files. Radiohead Airbag How Am I Driving Rare on this page. Please select the driver to download. Additionally, you can choose Operating System to see.

Click on update driver. Select the 'Browse my computer for software' method, and browse to the installation folder that was created when you ran the file. That will be located in C: SWSetup sp43656. Make sure the Include Subfolders box is checked and hopefully, the driver will install. Do the same thing for the audio driver.

Just browse to the different file number. If the audio driver doesn't install, go to the device manager, be connected to the internet, click on the multimedia audio controller and click on the driver tab, click on update driver and select the automatic search. See if windows update finds a driver that works. You should try to install the Vista fingerprint driver and see if that works. Try Auto or manual install. You can try the W8 Protect Tools software from this model and see if it registers your fingerprint. If none of that works, abandon all hope of getting W8 to work on your PC, and revert to W7.
