Issue with Stone Machines

[knelmes]

To close this one off, as far as we can tell, it was a problem relating to the NIC on the intel desktop boards stopping them from starting up with the LAN plugged into the machines, a couple of low profile cards later and we are having no problems with the machines and the shutdown problem has gone.

 

Thanks for posting about this, it stopped me thinking I was going loopy.

 

We're having the same problem with some RM computers - occasionally they won't turn on, take the network cable out and it works! Going to put in network cards to work around it. I was wondering what motherboard is in your Stone computers? Maybe it's the same. I'll find out what ours is.

The boards in question are all Intel Desktop Boards, I can get you some model numbers if you want when im back at my desk on monday, its happened on the newer boards and older ones, so im guessing its a possible common manufacturing fault or something that develops over time, the machines in question are all a little over 2 years old I believe, though Gareth may correct me, he knows the exact machine ages, it certainly solves the problem fitting a new NIC onto the machines as far as we are concerned.

Intel Desktop Board - E210882 - thats the Model Number I believe on othe older machines that were seeing the problem with

Thanks for that, ours is a ASUSTeK Computer INC. P5RD2-TVM/GB/1394, so not the same. Oh well, it's only on 3 of our computers so not a huge problem now I know the workaround.

To ressurect this thread (not sure if its allowed, but I do need some extra advice on this matter) - I am now seeing a new issue with these intel boards - their the E210882 / DG965MS boards, basically now on some machines, they refuse to start up at all, on plugging the PSU into the machines I can hear an audible but quite low "whining" noise coming from the motherboard, nothing at all boots up with them. I have tried everything as described previously, even unplugging any thing apart from the bare essentials here and rehousing everything on the machines, but they still refuse to start up.

 

has anyone got any further suggestions on the matter ? or is it just likely that the motherboards here have gone to a better place ?

RBendle, check the capacitors aren't bulging or leaking, the USB ports aren't damaged, you have a known working PSU and they are removed from the case when testing.

ok, thanks, ive removed the front header usb and firewire ports from the machines in question anyway, the back ports built in to the motherboard all look intact as far as I can tell. I would disable them if I could boot to them, but I cant at the moment.

 

No capacitators appear to be leaking or bulging on the motherboard I have on the desk here either, the PSUs I have here all test fine also, just same result on the machine, a low whining noise and no booting or anything when plugged in

We find it's normally the PSU failing, discharging all power solves the issue sometimes for a little while before eventually dieing completely.

 

Normally replacing the power supply works, but you seem to have already tested that :/
