crash - no log entries
I am fairly new to Linux but ok with computers in general. I am running a 64studio dist (umbutu kernel with tweaks) and recently box powers down without instruction. I can't find any entries in either var/log/messages or /var/log/syslog -- both just record 'restart' at the time I reboot. I suspect hardware but would like any advice on where else to look, monitors to use etc to help track this.
