    hi,

    recently I upgraded to win 10 because I had some wierd problems with 100% disk usage, and in the process I lost 12GB of ram... I have 8GB on board(it's a laptop) and one additional 8GB. I don't believe 2 ram sticks gone bad in the installation so whats the catch?

    PLS HELP

    According to the specs at the link below that laptop has 4 ram slots (2 user accessible and 2 not, I take that to mean you can get to the user accessible ones more easily !) and has 2 x 4GB ram sticks when new.

    Did you replace both of those with 8GB sticks ? Which ram slots is the present ram in and are they the same slots the original ram was in ?
    Is your Windows 10 64 bit ?

    no the 2 4GB sticks are the ones that came with the laptop I added one 8 GB stick. The laptop is at least 4 years old and it was working in this configuration for couple of years.... the ram dissapeared after windows reinstall... that's what makes it strange.
    The RAM that is working now is the original RAM that came with the laptop.

    How much ram is shown in the Bios ? If less than 16GB try setting the bios to default values and check ram amount again.

    Did you install the the 32 bit version of windows 10 or the 64 bit version?.
    If you installed the 32 bit windows 10 the maximum memory allowed is 4gb and the rest of your ram will not show

    Go to control panel>system and security>system. Post a screenshot of what it says. Here is an example.

    OK, if the bios shows only 4gig, that is all the operating system is ever going to see/use.
    Some things to try;
    1 Reseat all of the ram. Pull out each stick; blow the slot out with a can of air and reinstall
    2 Have you loaded optimized defaults in the bios? If not, do so
    3 Pull out all new ram and see if the bios shows 8gig [the original ram]

    Do use caution when swapping/installing ram. Pull out the laptop battery and remove the A/C pw plug. Press the ON button 2~3 times; all residual pw is now dissipated. Now you can swap/reseat ram.
