Sudden computer shutdown
#11
If it's an all-in-one like the iMac, I'd guess it's either your power brick or the internal cooling. Since it's not failing with the exposed power brick, it's likely that. Do you have an IR thermometer gun to check it's surface temperature?

Ah.. Got it. Thanks.
Probably even more difficult to get the heat out.

I was watching a guy on youtube clean the vents on an ACER AIO. What a pain. His had an internal power supply that looks like it has a 40mm fan.

Like laptops, these things have heat pipes from the graphics and CPU processor to radiators. These radiators get dust in them too.

That reminds me.. time to take my side panel off and blow the dust out with DustOff.

I got a blower to clean mine. DataVac Electric Duster. Got tired of the canned air. Got it from Cyberguys. Love that thing. It's got some power to it. Take everything outside, though! Learned that lesson the hard way.

looks very cool. I'm just out of room for one more gadget. heck, I'm mounting router switches on plaster walls because I'm out of horizontal surfaces to put things on.

Too much to take my desktop PC outside. I just wear a dust mask (those I have room for.)

I really think you hit the nail on the head with Paul's all-in-one. Heat.

Mongo,
I've got a 19" 12U (22" total height) desktop rack if you need to go vertical with your toys. Currently it is serving a multipurpose role as a knee-knocker/toe-breaker/dust collector. Holler if you can't live without it.

Thanks for all the input. The system was clean of malware and viruses, there was very little dust in the case and the power board checks out OK. So the likely culprit was the power brick, which was a bit warm (though not hot). I've rearranged things so the brick is now on the desk rather than under it and it has run OK for nearly 24 hours.

If the device(s) were made circa 2005-ish it may have bad capacitors.


Using FlashAir W-03 SD card in machine. Access through wifi with FlashPAP or Sleep Master utilities.

I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses. Big Grinnie

If it was made circa 2005 with those bad capacitors, I'd be amazed it survived this long! Big Grin
