Hi all
My dad (an electronics engineer of 40 years experience) once told me "intermittent faults are a swine to fix" - and never truer words were spoken. Could you all please take a look at my logic before I condemn certain parts of this failing box to the bin? 2008 vintage 64-bit 4Gig RAM machine running Ubuntu 12 fine for the past month - 28 days uptime as my media server and no problems at all. Today I switched the kvm box controlling it to control another machine (no disconnection, just a flick of a switch) and the box powered down! For some reason whenever the bad box powers down, it needs to be physically unplugged from the mains before it will come back up - this particularly baffles me. Brassed off with this, I started to look into what causes random shutdowns (it's not the first time it's done this but as I say it's been fine for 28 days). I left it running for 20 minutes in BIOS to check the CPU temp was fine - and it was at 44 degrees C max. Rebooted to see what dmesg might say but - post BIOS but before boot - it shut itself down. And at that point my anglo saxon became taboo for the good folks on this list! I'm now stumped and, as the machine is 2008 vintage (though good for its time) it might be time to upgrade - but I'm wondering which bits I can salvage. I'm thinking the following are ok to reuse: case, optical drive, hdd whereas any of the mobo, RAM and certainly PSU could well be the trouble and it's almost impossible to test which. Can anyone offer another diagnosis / treatment for these symptoms? I might be inclined to buy a new PSU and see what happens swapping that before any more major surgery but is there really anything I've missed as regards seemingly random shutdowns? Incidentally when I say shutdown - I'm talking immediate power down - not the OS executing a halt command. Cheers Rob Cheers ROb
