Arduino Heating up

I am working on a project including 2 servo motors and 1 HCSRO4 ultra sonic sensor. I have been using this Arduino Uno board for all my tests and I have been working on this project for about 2 weeks now. The Arduino worked perfectly fine for all this time. I even worked on it 20 minutes ago and it was working with all the components connected. But now when I try it, it gets heated up near the USB cable connection and the on light fades away when I connect the USB to my laptop. Can I get help with knowing what went wrong and any solutions?

Post the current schematic to see how we can help, simply.

I'd suggest you start by disconnecting all the external parts and run a simple sketch to see if the Uno is still OK.

Are you trying to power the servos from the Arduino's 5V pin?
