LEDs at PORTD are blinking about after 3 seconds
Is there problem with oscillator selection?

PIC 18F4550

void main()
{    TRISD = 0x00;
     while(1)
     {
      PORTD = 0xFF;
      Delay_ms(100);
      PORTD = 0x00;
      Delay_ms(100);
     }
}

Oscillator settings are wrong. Please zip and post the complete mikroC project files. I will set the oscillator settings properly.
 

To select 8 MHz INTOSC, OSCCON need to be written, presently default 1 MHz will be used.

And also IRCFx_bits have to be set properly. Look 4550 datasheet Oscillator section for IRCFx_bit values.
