too little info, need to see your code, if you need software reset, also if you read data sheet for your device, you will see config fuse settings for the like of BOR plus other reset commands.

Use pull-up resistor(tied to VCC) to /MCLR pin for normal operations and when a reset is needed then send '0' using, for example, tact switch tied to GND. RC circuit with tact switch is highly recommend for more quality design.
