Look for resetting the router. It will take rebooting the router and going to rommon and setting the config-register to 0x2142 which means ignore the start-up.

Hi

Reset the router, press " ctrl break " key, it will going in to rom mode, change the config register value"0X2142" by using config-register command , after it will skip nvram boot and you can change enable password in cisco, after that back to normal config value , so next time will login into router , with new password ,
