It could be anything....
Bit like saying "my car won't work". Could range from flat battery, through 'no fuel', onto much more major problems.
Start simpler.
Just do a 'toggle one pin' test program.
Then test if the pin toggles.
If it does, move on, and check the timing of the toggling.
Only once you have a pin toggling at the expected speed, go on to trying serial.
If it doesn't toggle, you are looking at fundamental things, connections, power etc..
