push and Hold the power button down while you push reset, keep power button pressed til it boots again. If it does not, and it's in warranty ship it to garmin. If it's out of warranty, have someone open it up and remove the battery for a couple of minutes.

Have you tried resetting the unit.Press and hold the RESET button on the bottom of the nuvi for several seconds,DONT use a ball point pen to do this,use something that wont damage the unit,if this doesnt work,do a hard Reset.Or try rebooting by holding the Power switch on for 15 seconds.Good luck.

This is for a Garmin Nuvi 760:
(From what you said, it sounds like you need a LCD+touch-screen combo)
First, you can find a new touch screen on E-bay for about 10-20 dollars.
The LCD+touch screens are about 60. If you just cracked the screen but
the display looks fine, you can just replace the touch screen.
Now,
for do-it-yourselfers. To open the back of the case, there are 2 small
torx (star) screws on the back to remove. If you don't have a torx
driver, sometimes just the right size eye-glass screwdriver can fit but
be careful not to strip the heads. Once those are out, you need to
seperate the back casing from the front. I used an old credit card to
pry gently with all the way around until it pops off. Don't force it,
just be patient, it will come off.
Next, I recommend unplugging
the speaker and battery so you can put the back aside for more room.
There are 4 more phillips screws on all 4 corners of the circuit board.
Take those out and the board comes out relatively easy. Don't force it.
Once it is loose, there isn't much room to play with because of the
ribbon cables. The large one is the LCD, the 4 pronged one is the
touch-screen. There is a lever that lifts up and secures them in place.
I got away with leaving them connected, but they are fragile and easy
to tear. Next is separating the silver plastic part of the case from
the black front that goes around the screen. I pried a bit with an
eye-glass screwdriver around the area where the earphone jack and
memory card go in. Again, using a credit card to pry all the way around
is best that it won't leave scratches. Don't force it, just be patient.
Once
you have that off, remove the screen from the case. I did it by pushing
with light-moderate pressure all around the edges massaging it out. The
touch screen and LCD have a rubber/leathery thin tape going around the
perimeter. On the front, I got under it with an eye-glass flat head
screw driver and slowly worked it around until it was free, being
careful not to tear it. On the back, I used a razor-blade to un-stick
it from the LCD, but be very careful not to damage the LCD screen if
it's still working. The goal is to get this off in one piece. Once you
have that off, there is the LCD and touch screen with double-back
sticky black tape holding them together around the edges. I used a
razor-blade. VERY CAREFULLLY separating them. Once that was done, I
carefully scraped the remainder of the tape off the LCD which was
un-reusable. I didn't know what to use for putting the new screen on
since I didn't have that special type of tape, so after raiding my
tools, I found some rolled butyl rubber for installing windshields. I
cut small pieces of this off and put them around the perimeter of the
new touch-screen (VERY THIN) in the same place the old one was, as if I
was installing a real windshield. This took much patience, but in the
end it worked great. Before putting the new touch-screen on the LCD, I
blew it off with some compressed air, being careful to never leave a
fingerprint on it while working on it. After putting it on, I pressed
softly but steadily to get the rubber to even out so there wasn't any
high points. Then, I replaced the same sticky tape that went around the
perimeter of the 2 screens the way it was. It wasn't as sticky, but I
made sure it was in place and it kept there by the pressure on the
sides of the screen casing. Make sure you get it on right, because I
think it's there as a shock-absorber so that the screen doesn't break
as easily if dropped or jarred. I plugged back in the LCD screen into
it's corresponding place on the circuit board and closed the tiny lever
that secures it in place. Then comes putting everything back the way it
was in reverse order. Be careful and go slowly, I ended up accidently
pulling the ribbon cable out for the LCD and Touch screen and had to go
back and reconnect them. This is a good time to attach the battery and
turn the GPS on to see if you have all your connections made securely
before everything is fully together. Put everything back together in
reverse order, remember, if you have to force it, then don't. Don't
forget to hook the speaker back up.
When it's all back together,
if the new touch-screen doesn't tap where you tap it, you can calibrate
it. This can be done by turning the unit off, then turning it on, then
IMMEDIATELY switch it to the right(lock) position before it boots up
and hold your thumb on the screen for about 30 seconds. There will be a
callibration routine that will tell you to push dots on certain parts
of the screen. If you do this with a stylus, it will probably be more
accurate.
Now hopefully, you will be more careful and not drop your nuvi again. I hope this helps.

Well, I had a similar experience with a nuvi 1300, and perhaps my solution will work for your unit.
I tried holding my power button for 10-15 seconds, which forces it to start, but mine (like yours), would begin starting, get stuck on "Loading Maps." and then shut itself off.
I had to plug it into a USB port of a PC, and it started up for the purposes of data transfer, (not the normal startup). I then unplugged it from the PC and it restarted properly.
Give that a shot and see if it works.
