It seems to be a cpu problem try do the following:
Seven beep code in Inspiron mean CPU Cache test failure possibly caused due to processor failure. Try releasing the residual charge from the system, here are the steps:

Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer including the battery and AC Adapter.
Press and hold the power button for 20 seconds.
Reconnect the battery and AC Adapter. Try to restart the computer and check.
If the issue still persists, you may consider replacing the motherboard.
