I had a machine with exactly that problem (which is comparable to what you're describing). This instant reboot could not be intendedly triggered, but it often happened when playing media files. As I assume, it was a faulty graphics card. Certain games would halt the system (and the last audio samples would loop in the sound card, making a buzzing sound), and it could also instant reboot when using mencoder to convert a media file from one format to another (for example, AVI to MP4). When run in headless mode (with the graphics card removed), the system did not reboot, crash, or halt anymore. Maybe you can do an "exchange test" with the components of the system? One at a time - replace power supply, RAM, main processor, graphics card, hard disk / SSD). --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
