If you suspect an infection then I would first go here
Kaspersky Rescue Disk 10 use the product info tab to download the ISO as well as the PDF manual. Burn the ISO to a CD, boot from the CD, use the interface to update the virus signatures (make sure you have a wired connection to the internet, although it will work with some wireless cards as well but not always).
I'm thinking with a driver like this "a5x6bp4w.SYS 7/14/2009 ) you're probably on to something.
You have a few other older drivers on board, but first let's make sure you're relatively virus / malware free and we can revisit those if Blue Screens persist.
Welcome to the forums and keep us posted.
