Since i brought my arduino, i used to plug it in my computer. Just within a minute, the board and tge Atmega microcontrollergets heated. I own a arduino uno rev3. What should i do?
It is faulty. You should return it for a refund.
Unless you have connected it in some way which has damaged it? What have you connected it to so far?
I declared the 2 pin as ouput, anolog pin as input, connected them. So that it will trigger my motor driver
I think they have soldered the microcontroller upside down. Because the text in the microcontroller does not match with the text' UNO'
On the board
You are powering a motor driver with output pin 2 which has a maximum current rating 0f 0.04 Amps? How much current does the motor draw?

Disconnect everything, then see if it stays cool. Run the blink program and see if it works. If this fails you have probably fried your Arduino. Post an annotated schematic showing exactly how you have wired it, be sure to show all connections, power, ground, power sources and not any leads over 10"/23cm in length. Post a lilnk to your motor and its controller.
Post a bright, clear, close-up picture of the board showing the component you think is upside down.

This is tge image and @JCA34F its a L298n motor driver. @gilshultz sadly i dont have a shematic diagram
Normally we do not have one either. It is created when we do the design. Generally it is generated as part of the design. The prototype is made from this schematic. As changes are made to the prototype updates are made to the schematic. We have no idea of how you connected it or what the connection on the computer was. We would assume USB which should be 5V. We do not know what part of the UNO is getting warm.
Drawing the schematic has cost the electronics industry money. Why because mistooks are found and chips are not destroyed by improper connections. Generally logic chips do not get warm, however there are exceptions but they are not on the Arduino UNO. When something gets warm it is because something is not making it happy such as reversed polarity, bad voltage, and many other things such as being previously damaged.
Why do I feel like DeJa'Vu when I see this thread? Maybe because of this thread which seems to produce that all over again feeling?
In your other thread I gave you a sample code to verify operation of pin 2. Did you ever run that? It is physically impossible to have the Arduino UNO Rev 3 chip installed upside down so no clue how you came up with that.
You make a schematic and post it along with links to your pieces and parts. You post your code using code tags. You just left your last thread hanging and now we have this thread? I wish you best of luck.

The first code is the code already present there. i run the code with a led and still the light glows dim without any blink.
