Hi Saqibsandhu1,

First, I’d suggest that you follow the steps mentioned below and check if still get the beep during the system startup.

1. Switch off the computer.
2. Disconnect the AC adapter from the system.
3. Remove the battery from the computer.
4. Press and hold down the power button for 15 seconds.
5. Then connect back all the peripherals and check if you are able to turn on the system.

Secondly, I would suggest that you run the diagnostics on the computer by following the steps mentioned below and check if there is any issue with the hardware on your system.

1. Turn on or restart the computer.
2. Immediately at the Dell logo screen, starting tapping the key once a second until the One Time Boot menu appears (if the computer boots to Windows turn the computer off and try again).
3. At the One Time Boot menu, press the arrow key to highlight Diagnostics, PSA+ or Enter ePSA, then press to begin the hardware Diagnostics.
4. Write down any error codes listed. Reply to us with the error codes.

Also, please consider reinstalling the audio driver on the system.

Please let me know if this helps.
