The obvious answers don't apply.  You have a 64-bit Windows 7 Pro system, so you should be able to use all (or nearly all) of your 16 GB of physical RAM.

Has your "Total Physical Memory" always been around 4 GB?  If not, what happened before this situation started?

You appear to have a custom-built system. 

• Did you recently install more memory? If yes, what did you install?
• What video card(s) is/are installed?
• What other expansion cards are installed?
• How much RAM is recognized in the BIOS?  (If you're not sure how to access the BIOS, there should be a popup message just after you power on the computer indicating what key to press -- at that time -- to enter the BIOS)

Please do the following.

1. Go here https://www.hwinfo.com/download/ and download HWiNFO.  Go to the left-hand column (Installer for Windows 32/64bit), place your mouse over the GREEN "Download for Free" button, and then click on "Local(U.S.)"  You should then download a file named hwi_608.exe  Run the file to install the program.
2. At the end of the install, run the program
3. When the program runs, it will open several windows.  On the window that has the tool bar with icons, click "Save Report" (the icon looks like a floppy disk).
4. In the "Report Type" window, click the radio button next to "Summary for Clipboard" and then click "Next"
5. In the "Short Report" window, click "Copy to clipboard" and then click OK
6. Close the main window (the one with the tool bar); all the other windows will also close
7. Start your reply here and then right-click > Paste the contents of the "Short Report"

My suspicions are that you may be running a Windows 7 32 Bit operating system.

You can access Basic Information by :

You can Right Click  Computer in the Start Menu.

Select : Properties..

In there it will tell you if its a 32 or 64 Bit Operating System.

This is what will be shown.
