I'm sure the adapter is fine and I'm not surprised you can't see any shorted pins. If there is damage then it is likely to be to one of the chips, internally. How this has come about, only you can guide us...
I have one of those dev boards sitting on my desk in front of me. So, I may be able to help you assess yours.
Do any of the LEDs light up when you power it up? With the factory image (what the board was supplied with), 7 blue LEDs illuminate on mine. Perhaps the most obvious one; does your 'POWER' LED light up?
If you're concerned about your board, don't leave it powered on for very long for the time being. Don't leave it powered longer than you need. The LEDs on my board illuminate within half a second of power up.

The power ON LEDs are getting lighted immediately and when we burnt our code which lakes leds blink, the LEDs do blink. The program is working fine but the FPGA is getting heated in 3 seconds ! very fast its becoming very hot . I fear if the FPGA will get fully spoilt if I leave it powered on even for a minute.
We are now trying to give less input current by changing the adapter and by using a variable power supply. The adapter that was given with the kit is 12v/2A . I thought of giving 1.5 A current. Will that help?
Actually we used a PLL to increase the frequency from 50Mhz to 100 Mhz because we are using a ADA board interfaced with the Cyclone 3 starter board. The ADA board has a DAC which works at 125 MSPS. So we used the PLL. Do you think PLL could be the reson for this unusual heating of the FPGA?
All other chips are normal and only the FPGA is getting heated up !
