We cannot help without knowing more detail. Show us your circuit diagram.
  • What kind of power supply do you use?
  • Is there a noticeable correlation of the reset with some other event (e.g. a machine turning on or off)?
  • What is "continually"? How often per minute or in which interval do the resets occur?

for power supply, I am using 7805 voltage regulator.
3 to 4 times in a second, due to which my program for calculating events in 1 second(frequency) can't calculate, as it goes again to initial stage of program

Can you confirm this is a hadrware reset? Or maybe it is a software reset?
Are you using any watchdog timers?
