Dell PC only detect 2 out of 4GB of ram

Hi, 

 

I'm having an issue with my Dell Inspiron 580 where it only 2 out of 4gb of ram, Windows 10 is very laggy now with over 80% of ram usage

 

PC specs:

Dell Inspiron 580

Intel core i5 760

4gb ddr3 ram(came with dell) - 1333mhz

1tb HDD

Nvidia gt220

cooler master 400w PSU( the original PSU died) 

windows 10 1903

 

troubleshooting steps that I have tried 

- reseating both rams

- try 1 ram by 1 ram

- try using slot1 and 2 on the motherboard to see if it's the slot issue 

- tried slot 3 and 4 - no post-  2 beep 

-ran built-in diagnostic( motherboard and windows) - no error found

Looking at the two beep code, In particular it means no ram is detected.

With that logic, I think you have a broken socket or CPU. Do you have other ram sticks to try?

It could also be the system is coming on 10 years old. (cpu wise)

That happens when the ram was put into slot 3 and 4( slot 3 is next to the CPU socket, slot 4 is the 3rd one from the left)

 

oddly when I tried doing another reseat, this time it picks up all 4GB of ram. Wanted to try memtest 86 but it wouldn't boot into it ( the only thing I can see on screen is _ ) update: turns out I used the wrong version of memtest86
