Help! New Build and No Video Display

[MrComputer]

Hello everyone. I bought a new motherboard (GIGABYTE GA-MA78GM-S2H), Processor (AMD Athlon 64 X2 6000+ Windsor 3.0GHz 2 x 1MB L2 Cache Socket AM2 89W Dual-Core Processor ), and RAM (CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit) to replace my old unit.

I put all this hardware in my old Antec case and nothing gets display on the screen when I turn it on. I was using the onboard DVI connection to my TV. I also tried using the analog connection to another computer display. Nothing.

Could it be the power supply? I don't know what to try next.

4 pin cpu power plugged in?

Pull 1 stick of ram

Case stand-offs right position for micro atx?

My Antec case doesn't have a four pin power connect. Just the 2 x 10 power connector. Is this required?

I did pull one stick of RAM out and nothing changed. No beeps or anything.

I'm not sure what you mean by "case stand-offs right position for micro atx.

Thanks for your help.
