GIGABYTE GA-MA770T-UD3P AM3 AMD 770 ATX

 And I am at a loss as to why I can not even get it to power up to the BIOS screen. It is definitely something on my end that I am forgetting.  I had the same issue with the first one which leads me to believe that it was either DOA or I was just to stupid to get it to work.

I can only think of it as 3 things. Not grounded properly (that plate on the backside of the mobo touching the case?) The PSU is not fitting correctly into the pins (OCZGXS600) It has plenty of watts and works fine, I know that for a fact. 3 being it is DOA.

Any help would be greatly appreciated even the most basic of suggestions or walk through since I am missing something common, I know I am.

Break it down to basics.

Take out the main board, lay it on some plain brown cardboard, use just one stick of RAM, and video card if you need it. and don't forget the 4/8 pin power connector near the CPU on the mainboard.

You made sure your CPU is on the supported list for the BIOS version the board came with?   (need more specs)

F2 BIOS or newer so it is probably not that since the current BIOS is F4.

 Example of external build

Follow CoolGms directions and you should eliminate incomplete connection, shorting and greatly lower probability of RAM problem.  If it is still DOA, I would consider PSU -- which is what I always suspect first -- and either motherboard or CPU (assuming you placed it in its correct orientation) DOA in that order. 

What video card are you using?
