Ok....I'm not sure what I did to cause this condition but I did it whatever it was. When my machine boots up I now get the message "Bios checksum error" and then at the bottom of the screen it says "F1 to continue or Del to enter setup" Problem is when I try to enter setup I get a blank screen w/blue bar across the bottom. My computer will still boot into windows and runs just fine but how do I get into my Bios?
