    I've built this computer within the last month, though in the past couple weeks I've been getting weird BSoD errors that have recently been getting more frequent. Yesterday and today I've been getting BSoDs with error code 7a, and I'm thinking that it's a problem with the SSD's flash memory controller, though I'd like to confirm that before I go ahead and act on Samsung's warranty. Any help?

    you have a number of different dump files which in itself can point to a hardware error although sometimes it can be down to a missing update or suspect driver or process.

    Check your Evo 840 is running with the latest firmware EXT0BB6Q.

    Run a chkdsk (it's fine to run chkdsk on SSD's as I also own an Evo so checked this out personally):

    BiosVersion = V1.6
    BiosReleaseDate = 12/02/2013
    Your Bios has an update pending:
    - Improved RAID card compatibility.
    - Improve memory compatibility.
    - Updated VBIOS and GOP Driver.
    - Supported Haswell-Refresh CPU.
    It's critical you ensure I have the correct web page for your motherboard so please double check.

    sptd.sys Thu Oct 31 15:26:53 2013: SCSI Pass Through Direct Host - Daemon Tools (known BSOD issues with Win7) please uninstall to test.

    If the bsod continues after making the above changes please run Memtest86. The latest version can be found here:
    This guide although a little old will show you how best to use it:

    Post any new dump files.
