    I'm getting the following errors while watching YouTube in Chrome on my MSI laptop. See attached diagnostics.
    DRIVER_IRQL_NOT_LESS_OR_EQUAL (wfplwfs.sys), dump file: 060214-24468-01.dmp
    KERNEL_SECURITY_CHECK_FAILURE, dump file: 060214-6781-01.dmp

    Something that may be noteworthy is I only had 1.5 GB of space on my system drive at the time.

    both dump files mentioned the above driver which could be noteworthy:

    bwcW8x64.sys Mon Sep 24 21:37:14 2012: Killer Bandwidth Control Filter Driver. A 2014 version can be found on the laptops web page here: 64
    Forgot to mention that you'll find it's included in the Lan driver.

    In fact try applying any of the updates which seem applicable to you including firmware and bios. Do make sure though that that is the correct page for your system.

    Regarding your HDD, your best trying to leave around 25% free. Otherwise things like pagefiles, system restores and indexing have no room left to manoeuvre. Try cleaning the system to get some space back (it can be amazing what you free up). This application is both free and good at what it does:
    Don't bother with the registry cleaner as Windows doesn't need one and more often than not it just leads to issues.
