    What happens when there is not enough RAM is that some data is paged to the pagefile to make room for other tasks, the pagefile is the virtual memory on the hard drive.

    In a simple explanation, with an IRQL of level 2 or higher a driver has access to certain areas of the kernel, however when the driver wants to reference an invalid memory address or a wrong memory address a pagefault occurs. With IRQL of level 2 or higher we move from paged memory to nonpaged memory, in nonpaged memory a pagefault does not occur under proper circumstances so when a pagefault occurs it is a violation of the rules and thus a BSOD occurs.

    Thank you for your detailed explanation, as these are terms I understand. This helps me get a better idea of what's going on with my own computer a little more. Would it be possible to explain briefly why a fault would not correct itself, and why it would cause windows to seize up and force a restart (IE: BSOD)?

    Windows cannot correct errors on drivers & hardware, what it can do is modify a few things of its own system but nothing more.

    If you know the function of the BSOD then you know the answer to your second question.

    Okay so I used WhoCrashed to analyze some crash dumps (a few from today) and the Intel Gigabit Adapter driver was the cause for a couple of them. Checked device manager and the driver is from may of 2015 even though I thought I had updated it after your prior post about which drivers were outdated. I am updating the driver as we speak and will see if it helps my issue with a couple less blue screens hopefully.

    Programs as WhoCrashed are a joke, they cannot analyze dumps properly.

    Okay so it's been a while, I have an update for you. I performed a blend test with Prime 95 with multiple failures indicating a lack of system stability (likely RAM). To rule out heating, I replaced my Hyper 212 EVO w/ seized fan with a Corsair H100i and performed a stress test with that. After 4 consecutive failures (four threads/workers) I have been since running a test with RAM stick 1 in Slot one for about 6 hours with no errors. I will continue stress-testing my memory in multiple configurations, one in each slot, until failure or 12-24 hours passes. I've seen RAM fail in single channel mode, but not multi-channel mode before (and vice-versa) so I will be on the lookout for such errors and test accordingly. I will update and mark as solved if I find and replace bad RAM successfully with no further errors. Thank you for you time once again.
