Powers on, Front white LED comes on, no startup sound

When powered, the system turns on, the front led comes on and stays on, but no boot sound. I have tried resetting the SMU. When I did this the front LED no long came on and all I got was a very loud full speed fan at boot up. I unplugged it for a day or two, and it is back to the original front LED and no boot. This was brought to me after a strong storm knocked the power out of the co-worker's house. Any suggestions for moving forward? I've scoured this site and many others looking for solutions.
