Hi greg,
I am sorry to hear you are facing BLUE SCREEN error in windows 8. I cannot say what exactly is the problem but i can recomend you to update your hardware drivers through HP website. You should also update your windows as soon as possible. And last not the least if the problem started after installing any particular program, uninstall it and see if the problem still exist. Also check the system requerments of that program and make sure it meets your current hardware/software configuration.
Thanks.
