Hello everybody! I have problem. I have 4,00 installed memory (RAM), but only 2,48GB is in usage. I tried BOOT Advanced Options to change it to 4,00GB, but nothing. I tried to find it on BIOS to increase, again nothing... Please I need to fix this fast as I can. It depends on my gaming career and my games are frame dropping and losing on graphic. Comment below the solution. Thanks!
