Hi SmartOval. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.
It could be a hardware beep code which is how a motherboard warns us of failures:

Update the Touchpad driver from the PC maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you also have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.
If that doesn't help then enter Device Manager reached by right clicking the Start button, go to Mice > Touchpad and then Driver tab. Choose Roll Back or if not present choose Uninstall, restart PC using keyboard to Ctrl Alt Del, on blue screen tab to Power Icon in bottom right, press Enter, arrow down to Restart, press Enter to restart to reinstall the driver.

Go to Settings > Devices > Touchpad to go over the Settings. Then choose Additional Settings which opens the Mouse properties box. The Touchpad software installs a tab onto it - usually the last one - that should have more settings to check, including a checkbox to Disable Touchpad when USB pointing device is atached. This prevents palm drag from causing the cursor to jump
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
