    BSOD before and after clean instal


    Hi,

    I really need some help to fix my problem
    My problem have begun because my computer doesnt want boot and no bios (makes the noise like normal start but nothing on screen and no bios - no usb detection) its because i decided to remove all the hardware (GPU-watercooling) and just keep 1RAM
    Nothing change and i tried to change the RAM to another slot and i finally boot on windows so i try with 2RAM doesnt work (strange) i try to switch the RAM like 1->2 2->1 and it works i dont understand why
    After that i tried with all my stuff (gpu - watercooling - 4x4go RAM etc ...) and a lot of bsod appear
    BSOD started on windows10, 2 day after installing a watercooling
    I decide to clean instal windows10 but the first boot failed with this 0xc000021a and never want to boot on the clean windows 10 so i decide to instal windows 7 and BSOD waited me

    Im not an expert but i really think the RAM slot on the motherboard come to death
    MEMTEST with 1pass (no time for more) 0 errors


    Ps : windows10 pro X64 - windows 7 pro X64

    Thx for the help

    Hello and welcome alpha mate you have indeed a memory problem and you need to run a memtest asap

    RAM - Test with Memtest86+ it MUST be 8 passes at very least an best doen overnight because it is quite lengthy. see pics for what to expect

    Code:
    BugCheck A, {fffffa80909d72f0, 2, 0, fffff80002938f1f}
    Probably caused by : memory_corruption ( nt!MiIdentifyPfn+23f )
    Followup: MachineOwner
    ---------
    Code:
    IRQL_NOT_LESS_OR_EQUAL (a)
    An attempt was made to access a pageable (or completely invalid) address at an
    interrupt request level (IRQL) that is too high.  This is usually
    caused by drivers using improper addresses.
    If a kernel debugger is available get the stack backtrace.
    Arguments:
    Arg1: fffffa80909d72f0, memory referenced
    Arg2: 0000000000000002, IRQL
    Arg3: 0000000000000000, bitfield :
     bit 0 : value 0 = read operation, 1 = write operation
     bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
    Arg4: fffff80002938f1f, address which referenced memory

    thx

    0 errors and windows is pretty stable since 2days but a memory problem doesnt disappear like that
    I think the RAM slot on the motherboard is the problem

    Well two things come to mind if there were errors they would show on that test and secondly if there were errors and it were a slot as you will see in the tutorial that you need to test the sticks separately in the different slots.

    So no errors with all sticks in and all slots tested with no errors means just that no errors - unless I am missing something here.

    Now I could be wrong but if you have swapped the sticks around then it might have just cleared a biit of crud form the stick and slot contacts.
    To clean the slots see this

    SLOTCLEANING

    Now as for the slots to clean them use a strip of old credit card(or any card thin enough some are better than others ) about 1/2 inch wide nipthe corners off one end - preferably round them offhold apiece of thin lint free cloth over the end dab on some form of alcohol -isopropyl alcohol (what we swab the skin with before an injection) is good and GENTLY swipe along the slots. (See picof stick for laptop slots)

    This can also be done for the GPU slot/s and also the contacts ofthe sticks or cards - not the stick but some lint free cloth of course. See mypic for the sick but please be very gentle doing it if you are in any doubt -please ask before doing it but I use this all the time and have yet to damageanything
