    The most recent BSOD happened on 4/6/2015. However, prior to that it happened on 3/13/2015, 2/13/2015, and 2/12/2015. I'm not a tech savy person at all, but I am worried for my computer. I don't recall exactly what I was doing when the crash happen. But I believe it was just me browsing the web. Hope someone can solve my issue. Attached are the four dump file logs of the incidents.

    First time this happened was on April 12, 2015. Since then, it occurred for a total of 4 times. I'm just curious as to why my computer would crash. I don't recall all the instances of what I was doing before it crashed, but I am certain it crashes when I am just browsing the web. Attached are the 4 dump files. Please take a look at it. Thank you!

    BugCheck A, {fffffa80e3df55e8, 2, 0, fffff800030e34f9}
    
    Probably caused by : ntkrnlmp.exe ( nt!KiTimerExpiration+d9 )

    Hi,
    out of the 4 dump files posted, 3 were like the above and one is a Bugcheck 1E. The causes for Bugcheck A can be:
    https://msdn.microsoft.com/en-us/library/windows/hardware/ff560129%28v=vs.85%29.aspx
    Bugcheck 1E is usually caused by:
    https://msdn.microsoft.com/en-us/library/windows/hardware/ff557408%28v=vs.85%29.aspx

    Unfortunately the dump file containing Bugcheck 1E was corrupted and so I couldn't get the exception code (the reason behind the crash).

    In conclusion the dump files do not mention a specific driver although that doesn't always mean one isn't involved somewhere along the line. It is possible that your issue stems from either a driver or Bios issue, a system service with Windows which has become corrupted or a hardware failure typically RAM. Oh I also forgot to mention that with bugcheck A the anti-virus app can also be a primary cause.
    Usually I can glean from the dump files which machine your using but unfortunately all I can tell is that it's a Lenovo presumably a laptop? I checked your drivers and they are in need of updating if possible. I say if possible because laptop drivers are supplied by the manufacturer and they are not always up to date. If you know the where to go to find the driver page for your machine I would check what updates are available. If not then post the make and model and I'll point you in the right direction.

    If you recently added anything new either software or hardware (this includes windows updates) then did it coincide with the start of the bsod issue? If so try removing said update.

    Check for corruption within Windows by running the system file checker. Find command prompt, right click on it and run as admin. Type:
    sfc /scannow
    Press enter and await results.

    Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:
    http://www.memtest.org/

    To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
    Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
    Run the test for at least 12hrs if possible unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.

    Post any new dump files.
