32-bit versions of Windows are able to use up to 4 gigs of RAM. However, at times they might report a smaller amount as usable. Try flashing your BIOS to the latest version. That fixes most of memory issues. Go to the manufacturer's website for the latest BIOS drivers.
Also from the screenshot, your computer has a 64-bit CPU. Try getting a 64-bit version of Windows.
the simple solution use the 64-bit version of windows.
the other solution is that , you use a VGA " graphic card " that used a shared memory and he is taking from your ram , and to solve this go to your "Bios" and search for " Onboard VGA " or what equals it , then set your amount of ram that the VGA can use as a memory .
