Recently moved into this house, built in 1994:
- Computer monitor resets: This happens periodically (possibly when large electrical appliances kick on like the fridge), but it also happens almost every time when a fairly proximate ~15w LED light is switched on. I have it on a MinuteMan UPS now, but it doesn't help. It is not on a circuit with any large appliances.
- TV resets: This also happens seemingly randomly, though again, it could be correlated with e.g. the fridge compressor. Again, no large appliances are on this circuit, nor is it on the same circuit as the monitor above. The TV peripheral devices (AmazonFire stick, Chromecast, etc.) are also affected (e.g. a movie will stop and need to be re-initialized, though that could be the result of the TV restarting).
- Bang/clicking noise: Sometimes at night I'll hear a single bang/click noise seemingly from the wall, though there are no nearby appliances of which I am aware--I think this noise may be correlated with e.g. the TV resetting (maybe I'm hearing the furnace jolt through the duct?).
Not sure if all of these are related, or if I should focus on resolving them individually. Given that the house is new to me and the electronics are not (and were working fine in a previous residence), I'm assuming it's the house's (or the community's) electrical problems.
Update: I've removed all of the lights from the hallway light that was giving the monitor problems. The lightswitch still affects the monitor, albeit seemingly less often.
