My system is listed below. I bought a new stick of RAM to see if that may have been the problem. My system sat all summer bcause of a slight mishap. I bought this new motherboard this summer, so I sent it back and it did the same thing so I decided it was something else. I didn't bother working on it till now. Anyways....If I put just the new stick RAM, the video card, and hook-up the ATX power connector, the case power switch, heat sink with fan and sensor, and the MSI diagnostic light, it immediately show the IDE initializing code, no other codes ever show up. My video card is good, tryed it on a friends computer. The fan spins normally. Anybody have any suggestions? Haven't swapped out the power supply yet, I can't do it till tomorrow.
