hi!
ive been thinking what the problem is because i dont know what it is..

this is my previous setup.

Processor : intel core i7 870
Mobo: p55a-gd55
PSU: win+700w
Memory: corsair ddr3 XMS3 2gb (2x2)
Graphics card: Msi n460 gtx cyclone

earlier today i bought a p55-gd85 to upgrade my mobo.(because it has SLI that the gd55 dont)
i setup everything and when i try to press power, nothing happens so i had to try and press the power button in the mobo.. it only lights the power led in the mobo.. no fan spin,no hdd,noise, completely nothing but that light..
can anyone help me pls?
