a bit hard to see what's going on
do you have a schematic picture?

also take a look at the resistor that is probably the current limiter for the LED in the top right corner
seems to me it is connected between ground and 5 volts!
there are only 10 types of people
them that understands binary
and them that doesn't

Have you made certain of the caps size used with the crystal, lots of people misread the value on the caps.

The Boarduino (and all other good designs) has four 0.1uF bypass capacitors, your circuit has none.

Don't you somehow have to supply power to the input of your voltage regulator?
