Asus G73JH: RAM issue

Hello,

It's been a year since I posted again. I'm having a problem with my RAM, last time I saw my RAM (CC Cleaner) it was 4gb and it should be 8gb.
I double checked with HWiNFO64 and it shows 6gb.
I checked it on my Task Manager and it shows 4gb.

This is the photo for what I am talking about. What is this?

I do not know how to open my laptop and remove/re-insert RAM compared to desktop. Last month I experienced BSOD and maybe that time one of my RAMs shut off.
I think for 3 years, my RAM did well.

What should I do? If I still have 6gb of RAM it is more than enough for me.

I am also open for upgrading my RAM, I found CORSAIR VENGEANCE 2 x 4gb and the other one is CRUCIAL 2 x 4gb which is $15 less.
Both are 1600 Mhz but will set on default speed depending on the processor being used.

Thank you,

If you want to try it there is an excellent video here that will help you get to the RAM. NOTE - 3 slots are easy to get to the 4th requires more disassembly. https://www.youtube.com/watch?v=Tp90M_N6dzs

 

Thanks Josea, I can't open this laptop lol I might destroy my G73
My worst case scenario would be sending this into a repair shop and buy a new RAM huhu.

I'm going to play Total War: Rome II which requires heavy machine. Seeing my RAM like this hurts lol.

I installed CPU-Z and it shows 6gb of RAM. My 4th slot was not detected.
