Asus G73JH showing 2gig ram

I believe it was after i updated to bios 211, my system specs now show 2 gig ram installed. It also appears in task manager and is quite obvious in my pc's performance. Is there something i did to lose the other 4 gig ram my pc had installed before? How can i reinstall it?

Thanks

 

Open it up and reseat the memory in the slot

 

That's a new one... go into the BIOS and reset it to defaults. If that doesn't work, try reseating your RAM chips.

 

Wow that's weird...today its reading the full 6 gig ram. Hopefully it was a one time thing. Either way thanks for the advice =).

 

Okay well it's now reading only 2 gig again I have found a link between when it does this though and other symptoms of this laptop. It seems that when it reads the 2 gig ram, she opperates fine. When she reads the full 6 gig, she will almost without fail bsod or randomly freeze. This obviously leads me to believe that theres something wrong with my memory/motherboard. I have tried reseating the 2 ram chips i could access but it did nothing. Please help, it seems these bsods and freezes are becoming more frequent and i just want a working laptop

 

You could try moving them around. I would pull them out, and work with one at a time to see if any of the modules fail. If any do, you know what needs replacing.

 

How do i get to the first one? do i have to disassemble the laptop every time between tests and if so how? Thanks

 

Chastity is spot on. Here is a link to a video that will help, don't forget your antistatic wrist band!

I would try removing the other three sticks first. That way you will know right away if the faulty one is the one that is a PITA to get to. If you're lucky, you won't have to disassemble anything.

 

Well I've played with the ram chips and here are the results as I remember:
(i'm labeling the ram slots 1 2 3 4 in order of access from top to bottom and chips 2 3 4 originally residing in slots 2 3 4, slot 1 having nothing in it because i have the best buy model with only 6 gig ram)
-currently running with ram chip 2 in slot 2 and chip 4 in slot 4, pc recognizes only 2 gig and is stable running.
-all 3 chips in their respective slots, bsods and freezes.
-all 3 chips in but 1st and 2nd chips rearranged, bsods and freezes.
-chip 3 in slot 3 and chip 4 in slot 4, bsods and freezes.
-only last chip under motherboard in, 1st time started fans, no boot. 2nd time didn't even enter bios.(Is this my problem chip/slot)..i sure hope not><

Well that just about covers it, any advice on these results would be greatly appreciated, thanks.

 

I'd say that "last chip" is defective since the laptop doesnt load windows at all with it.
The proper test procedure would be to test each 2GB dimm individually, eventually to pass several memtest passes on each dimm module.
Keep in mind that the 4 memory slots are paired two by two in a dual channel architecture. So if you pair a defective dimm with a good one it will happen exactly what it happens to you now: you either miss 4gb (2x2) or you get bsods

 

Well i guess i'll run memtests , i just dont feel comfortable completely disassembling my laptop to get to that last chip and i dont think i can rma it. the weird thing is it didnt used to do this very much before i updated the bios and vbios but i guess it was still developing. kinda at a loss of what to do =/.
