Installed new RAM, shows 8GB installed but still says (2.75GB)usable.

So before it used to say 4GB installed (2.75 Usable) now I got new RAM (4x2GB DDR2 800MHz RAM) from CEX, installed, (all are same speed and type and brand) turned on PC and well says 8GB installed, (2.75GB usable). I then opened up task manager, yup 2.75GB is max as it could go. I tried the msconfig solution, did not work, I tried taking out the RAM, mixing with old ones, reseating the, nope nothing. I tried taking CPU out and putting it back again, still same. Went into BIOS, says I should have 7168mb RAM memory avaliable. Unfortunatly my BIOS does not have the option to remap memory location or any of that. I basically tried everything but here is a funny thing I found out. You know when you open up resource monitor? Well I opened it up, went to memory tab and get this, it said "349MB free", but the weird thing was it said "4354MB reserved for hardware" and it keeps saying this no matter what. Should'nt it say for "reserved hardware2 max 100MB? Now I dont know if this is the cause of the problem but it could be. If any one could answer me with a solution, I would be very grateful.
Down here are the specs:
MEDION MT7 490G Desktop
Intel Core 2 Duo E6750 2.66GHz
8GB DDR2 PC2-6400 800MHz RAM, all sticks are the same (2.75GB usable)
300WATT FSP PSU
750 HDD Storage (500GB one drive, 250GB the other, No SSD)
Windows 7 Ultimate 64 bit
ASUS Nvidia GeForce GT 240 GPU
MS-7358 Motherboard

Trust me it is, it says there even, 64 bit operating system. And in the System Information says, x64 based system.

A way forward would be to boot a live linux dvd and see what that sees that will tell us if its a windows problem or hardware problem Try Ubuntu before you install it | Ubuntu tutorials

Ok I just did a Live chat with Microsoft. They did a remote access diagnosis, nothing is wrong with the RAM, they said the problem is that I need to update my BIOS. They said MSI will have more info. MSI does not have live chat, I tried emailing them, "page 505 something went wrong" error came up. I will call them tomorrow as tonight it is a bit late. But do I need any sort of disk to update the BIOS? Or can I just download it from MSI and install it here on Windows?

Its a funny chipset which is 32 bit but with sort of addons to emulate 64bit which could be a bios setting or maybe bios update. thatswhat a live linux will tell us it doesnt effect the c drive it boots all from dvd if that say all the ram its windows if it doesnt then its bios

There are many Linux brands. I like Lubuntu. Lubuntu
Download lubuntu-18.10 -64bits iso.
Burn a DVD or, with Rufus, make a USB boot able flash disk.
Rufus-3.4 portable

To find out what you have on your computer download Free Download HWiNFO Sofware | Installer & Portable for Windows, DOS
Extract and run (don't need to install). Post here an image of hwinfo window.
