In order to get a proper reply you need to be more clear and specific.
Which microcontroller you are using?
Post the code...
When you programmed the mcu did you study the data sheet and configured config bits / fuses properly, what have you done with the MCLR/RST circuit (depending upon the mcu)
what kind of micro(processor or controller) you are using?is it atmel,pic,8085?are you using adc,some kind of serial communication or keypad?please answer this and post your code.
binto You are the guy having problem with PROTEUS (https://www.edaboard.com/threads/201300/ )is this an after effect of that problems?
