    Hi I'm on Windows 8 64-bit on a Toshiba Satellite L750
    My computer has constantly been a pain and has not once been completely usable. There is always some sort of flaw.
    I deleted everything and installed Windows 8 last week because it seemed as though only 2gb of my 6gb of ram was being used, and I wanted to installed Win 8.

    Currently in the Resource Monitor I have 2 gb in use/free and 4gb of is labelled 'Hardware Reserved' and doesn't appear to do anything.
    I have spent the past two hours trying out different methods to get it to work, but none of them did, and on the forums I looked at there seemed to be no real solution and the threads just trail off into unrelated problems.

    I really need this 4gb to be active so I can actually use my computer properly and use the full 6gb of ram that came with the laptop. This problem has been around on Windows 7 and still exists after doing a fresh install of Windows 8.


    Thanks, and I really hope I can get this working for once.

    • Reset your BIOS to optimized defaults or failsafe defaults if you can.
    • Disable memory assignment options in the BIOS.
    • Ensure all RAM is seated properly in the DIMM slots and that nothing is blocking them.
    • Run MemTest86 and rule out corrupt DIMMs. If it shows errors at any time the RAM is faulty. This is a critical operation.
    Do you have 4GB of RAM on your graphics card? This would lend itself to a memory assignment problem or conflict.

    What other options did you run? What kind of RAM is it and are they all matching DIMMS with the same clocking? Best of luck.
