Help with Flash memory reading

Hi all,

I am using cyclone 3 starter kit. I am not able to program my flash memory. when i try to reset the factory settings the loading is stuck at 71% . in the programming window the FPGA name appears as none after 71%. But the same cycloneIII_3c25_noise _standard file, if i loaded it as .sof file it is getting loaded 100%. Looks like i have damaged the flash memory. One another thing is my FPGA is getting heated rapidly. Does anyone have any idea on what the damage to the flash memory would have to do with the heating?

Any response will be highly helpful !

thanks :)
