PIC mcu gets programmed but doesntdoesn't get executed

I am using 'pickit2' through Mplab to burn my code. Suddenly none of the codes (even blinking led) that iI fuse through it gets executed.

I confirmed whether it writes the hex code properly using the 'Read Memory' feature.On On comparison,I I found no change in the hex.

I changed lot of IC's (16f/18f) ,I I tried other boards too, but nothing worked.

WhatsWhat's going wrong with my setup?? please help me to figure it out..
