The second thing to check is if you have your RAM stick not inserted correctly, open your PC and check if the connections are alright!

How to Fix Usable Memory in Msconfig

Open your Run prompt by pressing Windows+R and type in msconfig, hit Enter.

Go to “Boot” tab and click on “Advanced options…”

Uncheck “Maximum memory” and click “OK“, restart your PC.

Upgrade/Flash Your BIOS Firmware

One of the best solutions you can try is to flash your BIOS using a firmware that you can download from the constructor’s website.
