3 beeps codes is a system board failure and 5 beeps is a CMOS battery failure.
Ensure you backup all imp data on the system first.
Update the BIOS if possible - http://dell.to/2g6cqpK- restart the system and check.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
If the 5 beeps issue persists, then download the service manual from the above link - remove and reseat the CMOS battery and check. Or replace the CMOS battery and check.
If the issue is unresolved, then I would suspect a motherboard failure.
