You need to go here and get all your motherboard drivers:

You will also need to download the correct "Audio" and "Video" drivers. Use the first link I gave you and select your model "Dell Dimension C521" by clicking on the proper selections in the menus that pop up and then look at the list of audio and video drivers and select the ones you have.

run sysprep under system32 folder, it will give you out-of-box Experience.

Maybe you forgot to install the audio driver.
Please insert the board driver into cd drive the install the audio driver.

HI,
The blue circle port is for audio. Green and black are usually inputs and pink is for mic

Thank you

You can either buy a Graphics card with HDMI/DVI on or purchase a VGA to DVI adapter from most computer retailers.

~Plug the adapter into the TV and the cable from the PC to the Adapter.

I think it's F12 or F10 on boot up will restore it to factory, beware it does put all setting and folders back to factory settings to, so any data will be lost, it will be just as it came out of the box.

Hope this helps

audio on pc green blue and pink.green is out go to speakers. i think blue is input where your keyboard connects. pink is for microphone. you will need a cable with red and white rca type plugs to connect to keyboard the other end has one mini plug to go to blue or input on pc.

make sure your volume isnt muted...and try both soundcard ports

In control panel, make sure that the mic is properly configured in audio devices (They don't always get assigned properly) so that the correct device is set for recording.

You can test the mic in sound recorder (Just type sound on the search bar, it should appear in the list)
