OK. When I hold the power button for 30 seconds after removing the battery and power cord, I replace the power cord and get 7 beeps and still no screen power. Immediately after the beeps I push the power button to turn off the pc and again to turn it back on. This works.

That being said, what exactly do I need to replace? I have already changed the memory. Is it the motherboard, the CMOS battery, the battery, the screen? Please help me figure out what to buy.

Using a Dell Inspiron 3520

Hi

seven beeps usually indicates a processor problem. It is very seldom that the processor actually fails, it is most likely a motherboard issue.

See if you can perform a Pre Boot System Assessment (PSA Diagnostic) by holding the “Fn” while rebooting the system. Keep holding "Fn” key until the diagnostic gets initiated.

You may get further info on PSA here:

Good luck
