Well, this could be any number of things, but I see this most often when a motherboard is grounding on the case. This happens when a peice of metal on your case is touching a part of your motherboard that it shouldn't be. What I usually try is taking the motherboard out of the case, set it on something non-conductive (a piece of cardboard works well), hook everything up to it and power it on. If things start running (CPU fan starts spinning, any LEDs on the motherboard light up) and I get any beeps[1], then I know that may mobo was probably grounding on my case somewhere. [1] Make sure you hook your cases speaker up to your mobo. Almost every mobo will spit out a series of diagnostic beeps if it encounters a problem. These beeps are usually documented in the manual that came with the board. What you're seeing could be any number of things, however. Other possibilities I can think of: * Improperly installed memory - maybe it's not in the slot all the way; maybe it needs to be interleaved; maybe you installed your DIMM in slot 3 instead of slot 0... * [Mis|Un]set jumpers. If your mother board requires jumpers for things like CPU speed, CPU voltage, CPU multiplier, etc, it won't start up if they're not set properly.
