"pom"! when switch on the main.


It is my new PC again :-(

Evary time when switch on the main (all parts of the computer set are still switch off) I can hear a noice sound like "bom!" from the monitor.

Is that normal? I have never hear such sound from other PCs....

You have the monitor set on standby?  What you hear is the monitor waking up, nothing to be alarmed about, when it recieves a siginal from your computer then it has to "turn itself back on"
OK, unlike your strange hard drive noise, a lot of new monitors, interestingly enough especially the good ones, come on with a loud whumpy noise.

I take it that this is a 17 or 19 (or larger) inch monitor?  Probably has a Sony/Trinitron tube?

I have an Iiyama with a Trinitron true flat tube and it makes a huge whump and the picture shakes and carries on like it is having an epilleptic fit or something.  It only lasts for barely a second and startled the heck out of me the first time I turned it on, but Iiyama said its supposed to do that.

My monitor's been making this noise for nearly three years now and I haven't had a problem with it, so I think you can safely ignore it.

Out of interest, was the PC you upgraded from a *very* old one indeed? Virtually every 17" monitor I've ever come across (and we have a fair few at work) make some sort of noise like this on startup.
I think all the digital monitors make the sound.
