ERROR:avrdude verification error content mismatch

Development Tools IDE 1.x

Hi Everyone
My arduino UNO recently started giving me this error whenever I uploaded my sketch:-
avrdude: verification error, first mismatch at byte 0x0000
0x0c != 0x62
avrdude: verification error; content mismatch

It resets every time I upload and the RX/TX leds do light up but it doesn't execute the code

I have tried uploading the sketch to another UNO board and it works just fine
Is there something wrong with my board?

Its problem with bootloader Crashed. Check all facing same problem. You need to upload booot loader using AVR pocket programmer.

isnt there a way to solve the problem without additional hardware?
