Your capacitors in the Crystal oscillator circuit are shorted to themselves and then to ground.  The holes are connected vertically.  You need to move one leg of each capacitor to the hole that is closest to the ground bus and then place the other leg of the capacitor into the ground bus.

Pin 1, reset, is tied to +5V directly.  You need to fix this circuitry.

These are 2 errors I have found.  There could be others.

But your reset push button does not work.

It is NOT wired up as is shown on your schematic.
