I have a system that recently died. It will not boot at all. I get a 01 Q-code which doesn't mean much. I noticed that the diagnostic lights mentioned in the manual are not going through their full cycle... from CPU to RAM to video(I think) then to HD. My system lights up CPU and then it goes out and the blue light for RAM comes on and stays on. I took out all 4 sticks and tried them one at a time. Results were always the same. Anyone have advice on what to do next? Is the mobo probably dead?
