Just checking; Are you running 32 bit or 64 bit Windows ?? It sounds like 32.

His screenshot and system specs show 64-bit Ultimate.
I'm curious to see the lower part of his System page to see if Windows is legit.

If it were 32-bit windows, he would only be able to use about 3.5 or less. Are there any settings in your BIOS to allow use of all installed RAM?

How much RAM is displayed in the BIOS?

If the bios shows 8gb then skip to the next step,if not then it could be a issue with the motherboard not reading it or one of the sticks has gone bad and can not be read.
Anyways have you tried checking in msconfig? Hold the windows key then press R and type msconfig and press enter or click ok. If uac shows up then press yes and enter. Go to the boot tab then click on advanced options. At advanced options check to see if you have a check next to maximum memory and if so how much does it say. If it does have a check next to memory with a lower number then 8192 then uncheck it and reboot because it is set to show less memory to the operating system.

Check to see if it shows 8gbs now, if it does not try checking next to maximum memory and clicking the up arrow next to the amount until it reaches the maximum that you can put it up being 8192 for a 8gb ram system. Should look like in my screen shot and once done click ok and reboot and check if windows sees your memory now.

If you still have issues or this resolved the issue please let us know.

The problem may also arise , If you install Windows without secureboot over a UEFI BIOS.
(I have experienced such a crisis while i turned off secureboot to install Windows 7, and System Properties showed 1996MB Memory. But I had 6GB Ram). Please check that too. Use Hardware diagnostic tool supplied by Manufacturer to check the RAM.
