Hello! It seems like you've put together a nice system with a mix of new and second-hand components. Let's try to troubleshoot the sound issue you're experiencing with your new build.
Here are some steps you can take to try and resolve the no sound issue:
1. Check Audio Connections: Make sure that your speakers or headphones are connected to the correct audio jack on your motherboard or case. Sometimes, plugging them into the wrong jack can result in no sound.
2. Check Windows Sound Settings:
- Right-click on the sound icon in the taskbar and select "Open Sound settings."
- Under "Output," make sure the correct output device is selected.
- Test the sound by playing some audio to see if it works.
3. Check Device Manager:
- Right-click on the Start menu and select "Device Manager."
- Expand the "Sound, video, and game controllers" section.
- Make sure your audio device is listed and does not have any error symbols next to it. If there's an error, try updating or reinstalling the driver.
4. Update Audio Drivers:
- Visit the motherboard manufacturer's website and download the latest audio drivers for your specific motherboard model.
- Install the audio drivers and restart your computer.
5. BIOS Settings:
- Enter the BIOS settings by pressing the specified key during the boot process (usually Del or F2).
- Check that the onboard audio is enabled in the BIOS settings.
6. Check Audio Cables:
- Make sure that any front panel audio cables are connected to the correct headers on the motherboard.
7. Test with Different Headphones/Speakers:
- Try using a different set of headphones or speakers to see if the issue is with the audio device itself.
8. Check for Windows Updates:
- Make sure Windows is fully up to date by checking for and installing any available updates.
If after following these steps you still don't have sound, there may be a hardware issue with the audio component on your motherboard. In that case, you may need to contact the seller or the manufacturer for further assistance.
I hope these steps help you troubleshoot and resolve the sound issue on your new build. Good luck, and feel free to ask if you need further assistance!
