Is the processor fan turning? HD acitvity LED lit? If yes then it could be attributed to a dirty memory card contact. Try to clean its plated pins with eraser. Just take out the memory card when the unit is turn off and unhook to a power supply outlet or UPS. I f still not then try to connect to the next mem slot with same specification.
Hope this helps.

Hi jayson_rees,
There could be many things that could stop the board from turning on, Determining if it works is like detective work. What I do, is take everything off the board to start. Then add the minimum to start a board to see if it will start. That's one drive (cd or otherwise) the CPU, and one bank of memory. (that's not a required eliminate, but it helps avoid beep codes) Also, make sure you have your pin's set on the board absolutely correct, or that could be your problem to begin with. Also, if your going to load a ide drive, make sure you set your pin setting correctly on it. Now, you should get the power supply on, and the cpu. If those don't power up, it's then either one of the five elements. The CPU, Power supply, Ram, Drive, or the motherboard. The next step is to replace each one of the first four to see if you get any change. If no change, then I usually get another board that I can test the first four, and make sure that they work. After that, then I say you have a DOA Board
Good Luck and don't forget to leave a rating.
Thanks
Mark
