Does anyone know how to fix a broke uno. My computer will not recognize it. I have tried everything I know how to do. I would appreciate it very much for your help.
Lou
Lou,
Please reread what you wrote. No one can possibly make any progress in assisting you as you have provided no information other than the board is an UNO.
Did it ever work, or is it new.
If new, does the LED blink.
What PC OS?
If Windows, did you install the drivers?
If it used to work, what did you do to break it?
If it never worked, is it returnable?
Not to be ugly, but if you are over 10 years old, please think before posting something so useless: to me, to you, to everyone that wishes to help but just are left frustrated by your post.

I am sorry for that. The less on the board are both fed. I am using Windows 7. In the device manager it says that it is on com3 and the use says com4. I hope this is enough information to help you guys figure out what is going on.

Did you install the device drivers for the UNO?
Step #4 here
I have tried that and still can't get the drivers to load.Being I am a beginner to arduino there is a lot of things I have to learn. Please be patient with me. What I can't understand is why both the leds are on.
Lou
You really need to go back and proof-read and correct ("modify") you previous posts to fix the typing errors in order for anyone to make any sense at all of it. If you mean the LEDs are "both" something-or-other, then that is a problem since there are no less than four of them, so "both" makes little sense.
The Device Manager says what? What is the "it" on COM3?
The IDE says what?
What else might you have plugged into the USB ports?
It might indeed be interesting to know your age.
Again I am sorry. My age is 63. I have been working with electronics for about 10 year's. As I have said I am new to arduino. The board has two leds and both are red when I plug them into my board and then into the computer. The ide says that the board is on com4 and the device manager it is com9. Also I can't find the arduino.inf file for the drivers. I a usb hub and into that I have my keyboard, mouse headphones.So if you need more information I will try to provide it.
Lou
Well, I am certainly not in a position to complain about that age! 
The UNO has four LEDs. The PWR LED will always be lit when it is getting power - though not a total guarantee of sufficient power. If no sketch is controlling it, the "L" LED will be lit, but it is expected that Arduinox ship with a "blink" program loaded to test, which will - blink - the "L" LED so if you have never managed to upload a program, that is odd. The "TX" and "RX" LEDs will flash during a successful upload process.
So what is the history of this UNO? Has it been used before?
What do you mean by "plugging them into the board"? I refer of course, to the LEDs already on the board.
Is it - and has it been so far - connected directly to the same port of the laptop, and not through the hub?
I am talking about the leds on the board. When I plug in the usb cable the leds come on red and stay red. What I meant by unplugging it was the usb cable. Its like the board is not communicating with the computer or the other way around. I bought the board from China somewhere.
Lou
Could you post a picture? (actually attached)

You will need to change the IDE under the Tools->Port to match the Device Manager, COM9.

Ummm, yes!
Just because a COM port shows up in the IDE does not mean that it is the Arduino - all operational serial ports are enumerated. If the IDE has found COM4 it should also find COM9 - and any other COM ports that were continuously present since you started the IDE.
It will not find an Arduino port that you plug in after you have started the IDE - if you plug something in after that, unless Windoze remembers it, it will not appear in the IDE and you will need to shut down all IDE windows and open it again. (Kind of standard Windoze procedure really! 
But this also unfortunately applies to Linux.)
Actually, with Windows 7 and 1.6.4, I can plug something in after starting the IDE and the IDE will find it. 
hello again
I have finely uploaded the pic of my broken arduino. I hope this is what you wanted.
Lou
You have a counterfeit! (Don't worry, I have one too. But never buy one with the green poly-fuse and the Arduino markings.)
What is the story about green poly-fuse and the Arduino markings?
Well, if you read the official Counterfeit page at http://www.arduino.cc/en/Products/Counterfeit , they say "If it has a green poly fuse it is a fake."
Ok, I see. Thanks. That is a counterfeit which is an infringement on the copyright as opposed to a 3rd party board which legitimately uses the same design and parts because it is open source (except the silk).
Isaac96:

So what do you mean by "never buy"?
Given that by and large, the counterfeits work and are usable, what is your concern?
Or are you presumably saying that one should not buy counterfeits as such, but avoid them in order to penalise the counterfeiters, and buy cheap ones that are honestly advertised as "clones" (or "compatibles")?
kjn4685:
I have finally uploaded the pic of my broken Arduino. I hope this is what you wanted.
With with such a blurry picture, there is not much to see, but the two LEDs showing are in fact the power indicator and the "L" or status LED. As I believe I explained (or was it to someone else?), if you have never successfully uploaded a sketch, it should have the original "blink" sketch running and the "L" LED should be blinking, but perhaps you did manage to upload something at some stage which does not do this?
Have you tried selecting the various COM ports in the IDE? Have you set the board correctly in the IDE? Was it in fact ever working; did you install the driver for it? Did it prompt you to find a driver and what happened then? Does it sound "Do-deep" when you plug it into the USB and "Da-doomp" when you disconnect it?
