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.
