Greg, I'm having this same issue now too :( except the computer doesnt randomly turn off but once its off its a real 'experiment' to turn it back on. ie exactly what you just described here > If I pull all the plugs out of the back and wait 5 to 15 minutes and put everything back in, then it powers up again.
I suspect it is the motherboard (a dry joint) as once its off sometimes when i move it it comes back on just as i move it On Thu, Jun 9, 2016 at 5:24 PM, Rinaldo De Paolis < rina...@connectedsystems.com> wrote: > Hi Greg, > > > > We had a similar problem with one of our Dell Precision T7610 desk tops > which ended up being a faulty motherboard. > > > > Cheers > > > > *Rinaldo De Paolis* > > General Manager > > * rina...@connectedsystems.com > > ý http://connectedsystems.com > > ( +61 8 9227 0416 > > ( +61 4 5107 6211 > > > > [image: cid:image003.gif@01CEF76D.CB77B900] [image: > cid:image004.jpg@01D0A81C.7EEDF8E0] > > > > *From:* ozdotnet-boun...@ozdotnet.com [mailto: > ozdotnet-boun...@ozdotnet.com] *On Behalf Of *Keith Knight > *Sent:* Thursday, 9 June 2016 5:21 PM > *To:* ozDotNet <ozdotnet@ozdotnet.com> > *Subject:* RE: [OT] PC powering off > > > > Hi Greg, > > > > A mate of mine had a similar problem where his (relatively new) PC would > randomly turn off and then not turn on again.. we tried swapping out a > number of bits (e.g. the power supply) and couldn’t figure it out.
