You can use a tool called Driver Sweeper to completely uninstall and remove the problematic wireless driver from your computer.
Once
it has been removed, restart your computer and install the latest
driver for your WiFi card by visiting the card manufacturer's website or
by checking the HP site for the latest Windows 8/8.1 drivers
I kept getting the blue screen with Driver Power State Failure error message and then my computer would restart. I found your product and it did not happen any more. I just purchased an anti-virus (kaspersky) and now it is doing it again. It is so frustrating. My computer is only 6 months old. It is a Asus desktop.
