    Greetings, I've recently built a new gaming PC and I got the ram, cpu and motherboard in a bundle from overclockers. Everything seemed fine at first but after a few hours I started getting a BSOD, seemingly at random, I can be playing a game for hours before it happens or it will happen whilst I'm browsing. This is the event log:

    Problem signature:

    Problem Event Name: BlueScreen
    OS Version: 6.1.7601.
    Locale ID: 2057

    Additional information about the problem:
    BCCode: 7a
    BCP1: FFFFF6FC8060D7E0
    BCP2: FFFFFFFFC000000E
    BCP3: 00000000AC395880
    BCP4: FFFFF900C1AFC01C
    OS Version: 6_1_7601
    Service Pack: 1_0
    Product: 256_1

    The minidumps are in the attachment. Any help would be greatly appreciated!

    Your first log shows BCCode "7A" and mentions "There was error with disk hardware" and "Typically caused by
    a bad block in the paging file or disk controller error". The second log shows BCCode "A" and mentions unable to read from a particular memory address. It mentions a driver file as being the probable cause, though from my experience, it isn't really a bad driver.

    Since these two errors are not the same and this is a new machine, I would start by testing your RAM using Memtest86: http://www.memtest86.com/
