After some weeks I tried to start my RPI again to setup a local NAS.
I knew there was Arch on the SD card so I just tried to start it. I connected it to a HDMI screen and it seemed to boot correctly. Then suddenly it crashed and seemed to reboot but I got nothing on the screen again.
I thought it might be a corrupt system so I reinstalled Arch (latest version for ARM) on the SD card and tried it again - same result.
I don't know why this happens. I can actually log into the system but about 30 secs after start it crashes.
When it starts all 5 LEDs are lit up but if it crashes only PWR and ACT remain lit up. FDX, LNK and 100 are off after the crash.
After that I disconnected everything except for the power cable and the ethernet cable so that I could control it via SSH - same crash as before.
I use a power supply from the RS store with 1200mA at 5V without any external devices attached to it. Only ethernet/power cable.
I don't think that it broke in any way. All the time it was stored in its pink plastic case.
Do you know any advice what could have happened?
I would start with raspbian to check if it is software problem.
If it will continue to crash then change power supply and SD card.
After that, if you will still get random reboots you can return your Raspberry PI because it is probably faulty one.
