Too little details about your build. Impossible to give any help.

My wild guesses:
1. Incorrect Atmega crystal.
2. It is Atmega644 and you've programmed/set fuses incorrectly.

Fuses are incorrect. You programmed your Atmega to use 1Mhz internal RC oscillator rather than an external crystal.
See
http://www.megadrum.info/content/programming-mcus for the correct fuses.

Leave all the fuse as they were by default and change CKSEL to "Ext. Crystal/Res, High Freq, Startup time 16K CK + 0ms"
