Speakers making loud pitchy noise
\015 My harmon/kardon computer speakers are making a loud pitchy noise when turned on. Even when I disconnect the speakers and plug them back in the noise is still there. The fuse still looks ok.\015
This is a problem in the surround section, replace caps c59 (10uf@50v), c63 (220uf@16v), c64(100uf@16v). Also check for any other caps in the area
If they are computer speakers try this: (remember i am doing this from a windows vista) on the bottom right hand of the screen there should be a volume key right click on it and click on playback devices then right click on your speakers and click properties and go to levels and turn down the volume from there and see does that work... hope this helps.

Woofer popping i have the logitech z-5500 set, and ever since i got it, its hasent been working properly. i havent been able to get any bass out of it, the control unit works though, as well as the speakers connected to it. it makes a loud popping noise, sometimes. the popping can go in and out, sometiems for long periods of times. most of the time, it doesnt make any noise. but when it does, its really annoying.

My Dell Dimension E510 is making a "whirring" noise. It whirls loudly when I turn it on, like something inside is struggling to get up to speed. The computer takes more time than usual to become operable and open programs. Then with the computer on, the "whirring" comes and goes, it is more quite, but more uneven. Sounds like it's going fast sometimes, then speeds up and back and forth. I've opened the computer and cleaned the dust out of it. That didn't help. HELP. VHS
So what could make "whirring" sounds in a computer? Motors. What has motors? Fans, Hard Disc Drives, Floppy Drives and CD/DVD ROM Drives. I can't think of anything else. It doesn't sound like a CD/DVD/Floppy drive because you would only hear the nois ... Dell Dimension E510 PC Desktop
