Did you copy the new image to both the primary sup and the standby? What procedure are following to upgrade?

What is the current IOS and what are you trying to upgrade to?

1. Console into the supervisor card and post the entire boot-up process;
2. Post the complete output to the command "sh version". If in ROMMON, post the complete output to the command "set".
