    Your pictures in post #20 and #30 are completely different.
    What was different between those post. Example: Different things plugged into the computer, phone, printer, card reader, ect. Something is changing.
    I don't believe you posted back the exact ram you are using. (Exact)
    Something else if your motherboard will allow it. You do have your motherboard manual don't you.
    **Remove all ram. Install one module of ram where the motherboard manual indicates. Check your hardware ram usage again.
    Then remove all ram again and do the same with the other module of ram and compare.

    Example; my ram
    KHX2000C9AD3T1K3/6GX
    Two packages of 3 modules.

I CHANGED NOTHING, no settings and nothing physical as stated in the original post the computer will just boot with all the ram available. I know that may be hard to belive but its the god honest truth and it baffles me completely

    I'm not doubting you, it's just weird. It's as if the PC is booting with the full 8 available, then something is turning on and eating half of it. We just need to figure out what's being turned on and eating half the RAM. It also seems to be hardware related as that's what the "hardware reserved" memory is for.

    I've asked for some help so hopefully someone with more experience will chime in.

    Until then.

    I have seen ram that is not seated properly do the exact same thing. That is why I suggested one stick at a time seated properly. That mistake was on my own computer. Made by me.

    Hi,

    Windows 32-bit version is limited to just 4GB of RAM.

    You are using a 64-bit version of windows. If showing 4gb hardware reserved, as it does,
    then it could indicate a faulty ram stick.

    I would firstly try re-seating the RAM, ensure they are free from dust, and seated properly.

    Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

       Tip
    Run these tests overnight, pay particular attention to #3 in tutorial


    cheers

    Dave

    thanks guys, it looks as though one of my sticks may have an intermittent fault, still not sure why its going h/w reserved rather than just not reading at all. Is this normal?
