    Ok, my system is:
    CPU: E8400@ 3.00GHz
    GPU: Gigabyte GTX560
    RAM: Corsair TWIN2X4096-8500C5 XMS2 4GB (two 2GB sticks)
    MOBO: Gigabyte GA-EP45-UD3L
    HDD: WD 500GB Caviar Black
    PSU: Corsair CMPSU-550VX
    OS: Win7Home Premium SP1

    I have been constantly getting BSODs (while playing games or just regular desktop browsing) with the same error:

    IRQL_NOT_LESS_OR_EQUAL (a)

    and all the memory dumps from crashes point to memory_corruption and occasional Windows kernel files, as
    the root of the problem.

    Here's what I have tried so for to figure out the cause(with no luck)

    1. Clean reinstall of Windows with all the important updates installed through windows update (including
    SP1)
    2. Downloaded latest chipset(from Intel) + GPU(from nvidia[whql]) drivers
    3. Ran memtest86 for 9+ hours (10 pass) with 0 errors
    4. Did CHKDSK /r with 0 errors
    5. Updated the BIOS to the latest version (through Gigabyte's website)
    6. Ran WD HDD diagnostics tool with 0 errors
    7. Loaded BIOS defaults with 0 overclocks present in the system.
    8. Driver verifier did not return anything

    I am running out of options right now !!! I do not know what to do ![​IMG]


    I am attacking all the memory dumps that I've gathered.


    I WOULD REALLY APPRECIATE IF SOMEONE COULD HELP ME OUT !!!??? [​IMG]

    THANK YOU !
