PC turns off when I connect an external memory / PC se apaga cuando conecto una memoria externa

[JavieraNJL]

I don't speak English, but I really need help so I'll leave my problem maybe a little poorly translated and in Spanish

Hi, today on my Pavilion 15-CW1003la PC they installed a Kingston Notebook 8gb 2400Mhz Ddr4 PC4-19200 Sodimm Ram Memory in the second slot, to have 16gb of ram. During the morning everything went well, I plugged the PC into the power, connected my external memory and there was no problem. When night came I plugged my PC into the power again and connected the external memory and my computer turned off, which seemed very strange to me because it worked all day, so I turned it back on and tried to connect the external memory again, this time my computer did not turn off but started to sound in a very strange and unpleasant way, so I unplugged the external memory. I have tried connecting the external memory without the computer being connected to the power and nothing has happened, it has not turned off or made any annoying noise. I have also connected my cell phone and my computer has also turned off. I have tried connecting the external memory to another computer and no problem has arisen. It does not seem to be a problem with the USB input since it does not generate problems when connecting a pendrive or a mouse, I even updated the USB drivers just in case but nothing has worked. My external memory is a Western Digital Elements 2TB.

I would really appreciate it if someone could help me.

Hola, eel día de hoy en mi pc Pavilion 15-CW1003la me instalaron una Memoria Ram Kingston Notebook 8gb 2400Mhz Ddr4 PC4-19200 Sodimm en la segunda ranura, para tener 16 gb de ram. Durante la mañana toda ha ido bien, enchufe el pc a la corriente, conecte mi memoria externa y no hubo ningún problema. Cuando ha llegado la noche he vuelto a conectar mi pc a la corriente y conectado la memoria externa y mi computador se ha apagado, lo cual se me hizo muy extraño porque funcionó durante todo el día, por lo que volví a encenderlo y probé a conectar de nuevo la memoria externa, esta vez mi computador no se apago pero comenzó a sonar de una forma muy extraña y  desagradable, por lo que desenchufe la memoria externa. He probado conectando la memoria externa sin que el computador este conectado a la corriente y no le ha sucedido nada, no se apago ni emitió algún ruido molesto. Además he conectado mi celular y también se ha apagado mi computador. He probado a conectar la memoria externa en otro computador y no ha surgido ningún problema. No parece ser un problema de la entrada usb puesto que no genera problemas al conectar un pendrive o un mouse, incluso actualice los drivers del usb por si acaso pero nada a funcionado. 
Mi memoria externa es una Wester Digital Elements 2tb.

Les agradecería mucho si alguien pudiese ayudarme.
