Weird behavior when turning off the lights.

[4hya]

I have noticed this behavior ever since I'm using my old pc.

my old pc and new one is located at the same place.
(As I just replaced it).

I've noticed this weird behavior when someone turns on the lights.
I'm having alarm sound that a device is unplugged, and when I turn off the light.
the same alarm sounds.

FYI.
the lamp is a flourescent lamp and it is beside the PC tower and the only thing that separates them is 2in. wooden wall. if you need a photo. I'll upload it for you.

is it the static discharge of the lamp that causes this?.

Reminds me of a very old Hitchcock movie named Gaslight with Charles Boyer and Ingrid Bergman.

Please relocate either the lamp or the PC at some distance from one another to test if the same odd behaviour continues. But weren't the old PC and the light located at the same place before you got the new one?

Could be Dementia

Describe the alarm sound your hearing. Bells, etc.

Could be hearing beep codes.

Describe the alarm sound your hearing.

The sound of windows when device is unplugged.

Actually. Even the ceiling lights cause this behavior. The old pc's location is the same with the new one. The lamp is mounted on the other side of the wooden wall. Then pc is placed on a metal mounting on the other side.

You should have a priest bless the house.

Tap your heels together, 3 times, and say there's not place like home.

Can't understand what is happening because I don't believe in poltergeists and ghosts. Since when has this strange behaviour started? There has to be a rational explanation if we dig deeper.

I think it's the little people!

Hey, when your digging deeper...be careful not to fall in it!

Hi,

Not to worry. The digging won't me in my premises.

Some questions:

• What country are you in? Is it 220v or 110v power grid?
• Is the lamp and the PC plugged into the same wall outlet or outlet strip?
• Are you using any wireless devices with this PC?
• What devices do you have externally connected (printers, external drives, etc.)? And where do they get their power from (wall outlet/power strip)?
• How old is the building you are living in (modern wiring or old wiring)?

Do you have a wireless mouse/keyboard or some other such peripheral connected to your PC? If so, what I think is happening when the light is being switched on is this. With a fluorescent light, when it is switched on, it usually flashes 2 or 3 times until it strikes and lights. Each time it flashes, a pulse of electromagnetic radiation is released, which, if it is not suppressed correctly, can cause interference to radios and other devices that utilise a wireless connection. My guess is that it is probably the starter that needs replacing, as its built-in suppressor might have failed.

Philippines. Our power grid here is 220vAC. Maybe that is tech enough answer to me. The electromagnetic pulse might cause this. I don't have wireless devs connected to the pc. But have 2 printers. 1 usb mouse 1 ps2 mouse. 1 usb gamepad. 1 usb cam. Wireless router is independent. So that is excluded from the equation

If there is a problem with the wiring inside the light fixture and it is plugged into the same power source as any of the externally connected devices then it could be causing a momentary short circuit or electrical arc that is briefly taking the devices off line. This would be a bigger problem than the PC issue as any electrical arcing inside a fixture is a fire hazard.

You could isolate which device is disconnecting by systematically unplugging them one at a time and testing. If you find just one device that is doing this behavior you can isolate which power source is affected and narrow down the cause.

I don't see how an EM pulse would affect wired devices, unless the cables are unshielded. That is why I am more focused on the electrical power issue.

I'll try all your suggestions.
btw, the electrical wirings are all connected at the same line. E.g. Pc ,monitor, printer , etc. and the light is wired independently. So they are not sucking up energy at the same ac source
