After swaping several parts, to no avail, I gave up on that. Thought I could live with some annoying messages. Then came spontaneus reboots, happening more and more often, and the rate of the NMI messages started to rise also. It turned out, that several capacitors were leaking, so I threw out the board. I've no way to confirm it, but I guess the NMI messages were caused by that, so it's quite possible that you have some power problems indeed. cheers, m. -- Marton Kenyeres - mkenyeres@konvergencia.hu KVG Konvergencia Kft.
