Inspiron 3521 (LA-9104P) No Display 4 Beeps [РЕШЕНО]

Hi, A customer brought me this laptop Dell Inspiron 3521 (LA-9104P) which isn't power on properly.
When I push power button lights on and indicate 4 beeps in 3 times. (Beep-Beep-Beep-Beep) X 3.
According to the Dell service manual it says this beep codes indicated Bad memory. But I have changed RAM cards and problem is still there.
Is it something relating to the BIOS ? or something else. Bcz I couldn't find any solution from anywhere for this 4 Beeps error.

When I take out RAM cards and turn on the laptop , power lights on and shut down immediately.

Reflash BIOS, check RAM voltages, replace processor.

RAM voltages are ok and I have already Flash the Main ROM but i Couldn't flash the EC inside the kb 9012 Bcz i dont have an apropriate tool for that. When i pull the Ram it gives 2 beep codes for " No RAM module in the socket" error. but when i Put a new RAM again its beeping. I found that 4 Beeps indicates "Memory read/write failure" according to the Dell Beep codes for Inspiron. Is this relating to the PCH?

I replaced the south bridge and everything works fine now. I think earlier chipset didn't receive memory readings properly. Thanks
