Laptop not showing RAM after Windows 10 Update

[TwistedPhayte]

So I seem to be have hit a bit of a brick wall after the most recent Windows 10 update. I'm running an MSI GE72 2QD Apache Pro which comes installed with 12g of physical RAM, suddenly after the update, it's only showing 4g of physical RAM installed. Which makes even less sense to me, because theoretically it should be paired RAM, so I should at least have 6g showing.

I've tried updating the BIOS, running a check disk, gone through my msconfig to make sure that Maximum Memory isn't checked off, and I'm FAIRLY certain there was no power surges. In short, I've tried everything I can think of and could use some help.

Download CPU-Z and see what it says for memory?

Also, check device manager if anything has a yellow exclamation mark.

Everything is saying 4g of memory. System, BIOS, Nvidia GForce, doesn't matter. All if it says 4.

Nothing with an exclamation point in the Device Manger either.

If it show 4GB in bios, is wasn't the windows update. Did you install the extra ram? check for loose connection
