Some time during the night my long running esxi 5.0 installation had shutdown. I tried the power button, but nothing happens. So I unplug power, wait a few seconds and try again. This time the mobo powers up and esxi starts to load, but on "Initializing scheduler" it just shuts down and the mobo does not respond to the power button anymore (not even if held in for a long time). Only unplugging the power will wake it up.
Ok, probably a bad memory chip so I ran memchk86, but it found no problems. So I insert the esxi 5.0 cd that I used to install with initially, but it too shutsdown when it comes to "Initializing scheduler".
So I assume this might be a hardware problem, but which component could it be? Any pointers on how to check for logs on a unbootable system is welcome.
Server is DIY with off the shelf components (AMD processor and ASUS mobo).
Update: Tried the esxi 5.1 boot cd as well, also shutdown at initializing scheduler
