Here is an update to the situation
I remove motherboard from case and i disconnected everything.I tested my evga power supply using the jumper,The fans started spining just fine pointing to an issue with the motherboard.I then tested the motherboard outside case .Motherboard only had cpu , standard cpu cooler , ram attached and i got same issue as i was getting isn't case
So I can conclude its not a matter of shorting or psu.
Most probably motherboard....If you guys have any suggestion do let me know
