Speakers do not work. What am I not doing correctly to connect it to a dell dimension 8300 computer

DVD write combo means just that you can burn CD-R's or RW's or DVD-R or DVD-RW's your correct in the first place. You can also burn Blue Ray disc's as well. Nice burner. John

Hello,

1. Did you have the correct audio-drivers installed on the system?
   
2. Maybe the speakers are muted in the audio settings?
   
3. You could try to attach some external speakers, such as an amplifier or a headphone to the laptop.
   

Greetings...

Make sure that the drivers are loaded properly, Start>Right-Click "My Computer">Management>Device Management. If you have any splats under your Device Management you may just need to reload the driver. Dell Dimension 8300 drivers are here

And also make sure it is plugged into the pink jack.

Please verify that your jumper settings on the new HD are set to Slave. If not move the jumper to the correct setting and reboot the PC.

It may need to have video drivers or motherboard drivers updated. Or video card needs to be replaced

This system supports ECC and non-ECC Rambus modules. ECC and non-ECC modules can be mixed but ECC feature will be disabled. Modules must be installed in pairs. multiple modules - PC800 the max is 2 GBs
systems tool...run disc clean up...put a check mark in every box, you don' need anything there as it is all copies you have elsewhere...
then defraggment also in system tools.
If you really feel like making that ole girl hum, do a complete reinstall using the latest drivers from the dell site. If you use your service tag number it will select the better drivers for your application.

• makes sure that the AC cord the you are using is compatible with the PC
• and the right output / input settings are correct check the power supply voltage settings
  

This is a simple problem. Please check if you have the proper drivers installed and goto audio mixer in control panel and see if volume for all the speakers are enabled and are full..

- I would think so that the network cable is unplugged to your computer. Just like a telephone cord,

Then what you have is a defective Power Supply.
