    in order to help you best we need to see the dump files created when the machine blue screens. If non are present then you'll need to change Windows settings so that they are created when a bsod occurs.
    Open the run application.
    Type sysdm.cpl in the run box and click ok.
    Look across the top of the system properties box for 'Advanced' and click that.
    Look for 'Startup and Recovery' near the bottom and click 'settings'.
    Near the bottom you'll see a drop down menu under the heading 'write debugging information'.
    In the drop down menu choose ' small memory dump (256KB)'
    Under 'small dump directory' make sure it says %SystemRoot%\Minidump.
    Click ok and your good to go.

    Once your sure you have some dump files (look in the main windows folder for a folder marked 'Minidump') run the app found here and post the results:

    In the meantime BCCode 1a or Bugcheck 1A is a memory error and can mean your RAM has failed. Windows does have a memory testing app but it can miss errors and the best app for the job is Memtest86.
    If you open the link below you'll see you can run Memtest86 in two ways. You can either burn it to disk or install it onto a USB drive it's entirely up to you. You'll then need to enter the bios to change the boot order so you can boot from either the Disk or USB stick you have Memtest86 on.
    You must test for at least 12 hours unless it becomes obvious there is a problem straight away.

    I also moved your post to it's own thread as sometimes it can run to a few pages so you need your own thread to save confusion.
