I recently bought a new case for my computer, and I moved all my old stuff over into it. Unfortunately, I cannot get it to post at all, even in the old case. Here's the weird part: Even when I have it stripped down to just the power supply, proc, and mobo, everything starts up automatically when I plug in the power supply. Also, I cannot get it to turn off, even after shorting the pins where the power switch connects. Any thoughts? It's an Intel board with an old P3 500 (don't laugh).
