Please stop SHOUTING.

If the oscillator is not running, the rest of  your questions are null and void noithing can work if the oscillator is not running.  Any controller when it comes up ( and is not defective) will have the oscillator running or nothing could work.

Two possibilities
1) permanent reset
2) defective chip
