Monitor occasionally makes a "trilling" sound

When the computer processor is working hard I get a feedback sound out of my monitor speakers. A "trilling" sound is the only way to describe it.

Cheap sound card. upgrade to an audigy or even a sound blaster. You can try reducing the volume control on the internal mixer from all the way up to about 2/3 and that will help. If it's not up all the way on the main volume already- then the sound card is cheap- and has no filtering on the inputs. A better sound card generally fixes this.

How to build a or assemble a computer and troubleshoot?

Building a computer will require: a motherboard, a processor, memory, a video card or motherboard with onboard video, a sound card or motherboard with onboard sound, at least one hard drive, a CD or DVD drive, a case for the computer components, a power supply, fans to cool the computer, an operating system, a monitor, speakers, keyboard, mouse, 2-3 hours to assemble the computer.
You must ensure that all of the components are compatible with one another. After receiving the parts, lay everything out on a large, clean surface. Make sure you are grounded by touching a metal surface; this will prevent the transfer of static electricity to your computer components.
Typically, the steps to install the components are as follows: 1. mount the power supply in the case, 2. mount the motherboard 3. lock the processor in the socket on the motherboard 4. insert the memory sticks into the slots on the motherboard 5. mount the processor fan on the processor 6. insert the video card into the applicable slot on the motherboard 7. insert the hard drive into a hard drive bay in the case, 8. insert the CD drive into a CD drive bay, 9. mount any fans you have to the fan cutouts on the case 10. connect all applicable data cables to the CD and hard drives 11. connect all applicable power cables to the motherboard, video card, processor, hard drive, CD drive, and any other components. 12. connect the front panel USB, power, lights, and reset connectors to the motherboard 13. close the case 14. connect the power, monitor, speakers, keyboard, and mouse to the computer
Because this process is rather involved, I recommend following a guide such as this one:
It details the process, includes pictures, and even provides a list of compatible parts.

Speaker is not working properly , rattling noise coming

Can you hear any rattling inside if you shake the monitor? It can be blown speakers or they are being driven too hard, just want to make sure before taking it apart. Do not expect too much sound from monitor bulit-in speakers since they use very small speakers that sound like tin can for most application.

Hi, my Dell Vostro 200 monitor isn't working; when I boot up the light is blue and everything else seems to work but the monitor says 'Entering power save mode' or something and it shuts off. I can't get...

Your monitor is most likely fine. That message is the monitor telling you it's not getting any video signal from the computer.

If you're hearing all the sounds that go with a normal startup (usually a beep from the motherboard, then hard drive activity, finally the normal Windows startup sound through the speakers), and seeing that message, then you may have a monitor problem. You can try another monitor as a test.

The trouble is probably that the computer is turning on, but not actually starting up. This may be due to power supply, memory, processor or motherboard problems. Or one of the drives or expansion cards connected to the motherboard may be keeping the system from starting.

Make sure the memory modules are firmly seated in their sockets, and disconnect everything else but the power supply. If the motherboard, processor and memory are working, the system will start and you'll see something on the monitor. Then you can start reconnecting parts and see when the problem returns.

Hi everyone, i am a vcliast and have been singing

The speakers MUST be in front of and pointing away from the microphone.

I don't know what you mean by "crystalized" as that mic is a dynamic type.

If the speakers are in back of you you WILL get plenty of feedback. If you must run that way, then you need an anti feedback processor. The device shifts the pitch slightly so that feedback can't occur.

Can't get sound on monitor

First make sure that your speaker wire is plugged in to the correct port on your computer.

The speakerwire should be plugged into the green port.

Then make sure that the volume is turned up on your monitor.

Then on your computer.

If this is isolated to only your new monitor and the above solutions do not work there is likely a problem with your new monitor's speakers.


Feedback is appreciated!

Feedback sound

If moving the microphone doesn't work then suspect "microphonics" where a loose electronics component is vibrating and acting as a microphone. Could be cable. Unplug all microphone cables, still feedback? Right click speaker icon, sound properties, temporarily disable computer sound input devices. If still feedback then analog section of sound card (or motherboard sound chip) or your speaker system.
