help mobo is humming

[thop]

i turned my PSU off today for the first time in 3 months or so cause i was doing some stuff in the case.
anyway i turn the PSU back on, press the power button but nothing happens. turn PSU on/off back and forth, same with power nothing happens.
suddenly i hear a rather high pitched noise that sounds like a humming bee charged with current. not very loud, only hearable if you put your head next to the case (or in the case). went to the kitchen, came back noise is gone. pressed power, system POSTs.

turned PSU off/on to verify and the bee was back! couldnt power on the system either. had to wait about 3 minutes till the noise dissapeared. the noise is originating somewhere around the ide connectors. i noticed that above the AGP slot there seems to be a quartz clock gen? could that be making the noise?

and why cant i power my system on till the noise is gone i want to get rid of that fricking bee

Err... it's humming?

What tune?

On, or off key?

Could be your power supply going bad.
Are there any dodghy looking capictors anywhere?, swollen or leakening?

[Wombat]

Yeah, another vote for cap leakage. Almost anything else will just break or burn - caps will physically distort or leak.

At any rate, I wouldn't turn that system on anymore, or you could lose components in a power surge.

Your motherboard is humming?

RUN!!!!!!

thats bad news if i ever heard any no chance i can get myself a new mobo at the moment.
i checked all capacitors, they look fine (i've seen blown capacitors on a ECS K7S5A before).
are capacitors actually soldered or just put on those two pins you can see when you bend them (dont worry i didnt )

[Wombat]

Those pins are part of the cap.

If it starts counting down then i agree with KvH!

LOL!

Is the Weekly World News a serious paper? Can people actually believe this sort of crap? I bet some do.

[Kurt]

Excellent newspaper. Goes right along with Globe...

[thop]

so any chance to replace the faulty cap if i find it?

[Tjalfe]

OLd news, I am not sure, but there seems to be a growing problem with faulty caps.. all because of a stolen formular for the electrolyte in the capacitors

Caps are easy to replace. I don't know what kind of electronics stores you have in your area though - getting the replacements may be the hard part.
