Note: this is not a request for troubleshooting help.
For the past few years my 10ish year old “smart” TV will maybe once a week or so completely lose the ability to play sound in the Youtube app, and only in the Youtube app. Sound works just fine everywhere else. Bizarrely this is always triggered by an ad and never a video. Restarting the app doesn’t fix it, and neither does clearing the cache. Fortunately doing a full restart of the TV fixes it, it’s just irritating to have to restart because an ad somehow broke the sound.
What technological gremlins haunt you?
My PC just won’t turn on if he is cold. No, it is not “humidity is high” or too low temperature. It just doesn’t turn on if he cold start. A little of heat on the mb and he turns on like nothing ever happened. Already replaced PSU, CPU, GPU, HDD, fans. So surely it is just a feature of my mb.
Next time it happens unplug the front case connector and short the power pins. If it comes on, replace the power switch and wires.
That’s funny, same thing here. I’m very thankful to the stranger on a forum who suggested “blasting the motherboard with a blow-dryer.” Now sometimes I joke that my PC is diesel-powered.
I had a similar issue until I bought a different PSU that was slightly higher capacity. Not sure if it was some cold start GPU power draw quirk but that’s the only thing I changed and haven’t had a problem since.
Yea just sharing my anecdote since not a lot on google about it. My thought is it’s probably some combo of the CPU and Mobo not liking the level of cold. There was a Linus tech tips video on overclocking with liquid nitrogen and one of the quirks is computer won’t boot till you warm it up again.
My tinfoil hat theory is something in the mobo/cpu self shorts/disconnects when too cold and just depends on the silicone quality you get for that number of cold before it needs the hairdryer treatment.
Similar here: a boot from power off will ALWAYS mean there’s no network, but a warm boot will always work.
As a workaround, I always hit the reset button two seconds after turning the computer on.
I can tell there’s been a power outage if the computer is on and has no network.
It sounds like a defect.
I would vote (in this order)
- Bad solder joint
- Failing chip
- Bad capacitor
Bad capacitor moves up on the list if it wasn’t happening and is getting more profound or if you are having other stability issues.
While I bet you have had it for a while, thiswould be enough for me to try a warranty claim. The problem could lead to other issues.
