    Today, same like yesterday, my laptop rebooted instantly while I was browsing (Chrome), editing a txt file in Notepad and had mIRC open. I looked in the system event viewer and was able to find a message that says:
    Code:
    The previous system shutdown at 14:48:25 on ‎3-‎1-‎2014 was unexpected.
    I am not sure how the other messages in the event viewer relate to this improper shutdown, or how to troubleshoot the problem. But I could post them here if I know how I can do that in a neat fashion...

    Please help me find the reason for my PC rebooting so unexpectedly.

    Recently this started with me, i will be investigating by reformatting my pc and installing one by one driver as its 99% caused by an incompatible driver..

    Steps:

    1- reformat
    2- reinstall one by driver by another, after each installation open cmd as admin and type verifier.exe /all and restart if no problem continue.

    Do you have Windows setup to create a dump file on crash? It should be configured by default.

    Let me guess, you were about to watch or busy watching a flash video ?

    Flash player, 8.1 and AMD = PC Reset or BSOD

    besides in Event Viewer, look at events before the shutdown, that is what will clue you in...

    Normally that dump files are located at:
    Code:
    %SystemRoot%MEMORY.DMP


    But be aware that not every time a dump files is created!

    Also be aware that those dump files (if created) could be quite huge up to several GB!!

    In addition to it being a driver issue, don't overlook an actual hardware failure - hard drive, memory, video card, stuck or blocked fan resulting in over heating.

    Whoops, I see now it is a laptop, probably not a video card problem.

    hard drive - chkdsk, sfc /scannow
    memory - memtest86
    over heating - SpeedFan

    Set the crash dump file to "small" (or whatever they call it). As pisthai said, full dump file is huge. Use Bluescreen Viewer to examine.

    Windows 8 does run hotter than win7 because it does more at once with multithreading.
    Reboots are often a power issue or an overheating cpu issue.
