All it takes is some noise on the circuit to cause a flicker because of how the dimmers work. I’d try replacing the power supply in the computer and see if that solves it, since it would likely be cheaper than an electrician and it never hurts to have a spare power supply.

Why is my lights flicker circuit?

There are any number of potential problem areas: a switch failure, loose fixture wiring, worn connectors in the breaker box, or loose service conductors in the main electrical panel. Contact an electrician ASAP if you suspect loose wiring or haven’t found another cause for your flickering lights.

How do I stop my lights from flickering?





Tighten loose bulbs
If your light bulbs are flickering, turn off the power and, using a glove to protect your hand from heat, screw the bulb in more tightly. If a light bulb is in too loosely the socket isn’t making proper contact with the bulb, and that can cause intermittent flickering.

Can flickering lights cause a fire?

Yes, flickering lights can be a warning sign that there is a fire hazard in your home. When lights flicker all over the house and are not associated with a large or major appliance, such as an air conditioner, turning on it could mean that there is an issue with the wiring, which could cause a fire.

Why do lights flicker at night?

It’s the movement of air (or turbulence) in the atmosphere of Earth that causes the starlight to go a little rogue. Hot and cold air gets in the way and bounces the light around as it travels from the star in the distance through the atmosphere and down to us on the ground.

Why is my light bulb flickering when turned off?

Flickering can also occur when a LED lamp is switched off. This might be due to possible returns of currents from drivers, power supplies or transformers in the system itself. A further cause could be found inside the corrugated pipes: if the cables are tight together this could represent a big issue.

Why does LED light flicker when turned off?





When the power supply to an LED is switched off, the light output stops instantly. So if connected directly to an AC mains-electricity supply, an LED will switch on/off 50 times each second – enough to be visible to the human eye. That’s why some people think LEDs flicker more than older light sources.
