Are you connecting the fans to the header or are you using molex connectors? Sounds like a PSU issue.

i am using molex connecters for all the case fans.

Ok that runs seperate of the Motherboard. I believe you have a bad Power Supply. Recommend you purchase new one.

Make sure you are connecting to the correct front panel headers. Try bridging the two red headers next to the memory with a screwdriver. If it powers on and it doesn't power on when you have the case button connected to it than you have a faulty case button. We also see people connect the front panel connections to the serial headers sometimes.
