Display screen makes noise

Postby Jordy... » Thu Sep 06, 2012 7:36 pm

My computer screen makes a weird noise when I move my mouse and it also rattles/beeps/makes weird noises inside, anyone have a idea what this might mean and how it's caused?

Bad shielding or, especially if the noise only started recently, your power supply is slowly failing. Every time you move the mouse, the CPU wakes up from its sleep, consuming some amps more. That puts a different strain on capacitors and sends out magnetic fields and stuff.

What do you mean by bad shielding? It was before as well, but it got worse I think. It could be that the plug-in box is bad or do you mean internal power-supply?

If it's a samsung it might be their cheap capacitor problem.

You always want to have the software volume set to highest (windows, youtube etc) and reduce your speakers or headphone volume down to a comfortable level. This should increase the audio signal and reduce the 'noise' coming from the hardware to your speakers.

About the monitor, try playing around with the brightness levels of both the monitor and your graphics card software.

Couldn't you elaborate this, please ? Did you mean that dying capacitors act differently under the same power input and this causes the issue (how ?) ?

Capacitors themselves sometimes make noises, just like speakers. Except... they're not meant to do and it usually is a bad sign. Of course, then the sound comes from the circuit itself; if it just comes from the speakers or over the headphone jack, there is nothing to worry about.

Have you tried turning it off and on again?
