I have test it with 2 different power supplies, 2 different DP45SG motherboards, another regular old PCI video card, 2 different monitors.. and by testing all this multiple times I rulled out everything except processor, memory and video card compatability. Was quite unsure about memory cuz mobo guide says it needs non-ecc and unbuffered memory.
So my motherboard responds when i put no memory in, power is connected properly, BUT nothing on the keyboard or monitor happens..
If anyone has free time, could someone please give me a hand in resolving this issue, thanks in advance.

If nothing will come up but the fan spins than check your memory first try re-seating it first only one ram at a time in diffrent slots than if no boot than try a diffrent ram all together and if still no boot than check your cpu it may need to be replaced. Good luck. If no post and your board is working than it is your cpu or memory.
