Hello! I had a simmilar behaviour when I had the processor module upgraded and it wasn't connected right. The Power-up stopped because the system didn't find the processor, so the power button was lighting up only for an instant. There could be a thousand reasons for this failure though. I cannot help you here because it could be almost anything, including the power supply. You would have to troubleshoot thouroughly to find the source of this system failure -- maybe a piece of hardware (a chip, a transistor, a soldering) in the worst case, and maybe just dust or a loose connection as the best scenario. When I had such failures in the past (using IBM compatible PCs at that time) I used to disassemble the whole thing, clean it, and put it back together, using only the really required parts. If it worked again, I then put back all the non-essential stuff like additional expansion cards (PCI cards) -- one by one, to check if one of them was broken and causing the trouble. I whish you good luck! I hope I was of help, at least a little bit.
