I bought a newish laptop recently it came with stock windows 8 and UEFI bios I downgraded it to windows 7 and booting it in legacy mode. The problem is that all it's RAM it has which is 4gb is showing up but only using 1.60gb and the rest according to the resource manager, is reserved for system hardware some 2435gb of it and I know that is not normal. I like to know how to fix this in getting my ram back? I tried resetting ram sticks but it still only uses that 1.60gb out of 4gb of ram. nothing else is hogging the computer the IGPU only uses 512mb of vram. There is a hidden 1000mb partiton on the hdd system reserved and I checked it's not recovery backup. What is it I have no clue Any help would be great.
