    You could do a factory image recovery and see if the system is more stable. It is up to you.

    We should check the new RAM to make sure it is compatible with the old RAM.
    • Download and install CPU-Z and Upload screenshots of the CPU, Mainboard, Memory, and SPD tabs. In the SPD tab, upload an image of each slot.

    Screenshots attached. The PNY is the new memory module.

    I am thinking it may be a good idea to run with one module, then with the other, and see if you get crashes with each. I do see that one has higher frequency capability, and that may be causing some conflicts. Often, when RAM is bought at different times, even if it is supposed to be identical, the voltages and timings change slightly from the older RAM to the newer. That may be what you are experiencing that is causing conflicts.

    As you add and remove hardware, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.

    Once these steps have been followed, it is safe to remove and replace components within your computer.

    Understood. Will remove a module, reboot, and report back.

    VMT returned no errors after multiple passes.

    Original OEM module removed. PNY put in its place. Should I run any specific tests to A/B these modules?

    Also - I almost forgot... I removed Avast from my system, and am now running MS Security Essentials.

    No specific tests. Just do what you normally do that causes crashes, and if the crashes are random, do your normal routine for twice as long as it usually takes to crash on average.

    Right on. Will run more tests in the meantime.

    Just went BSOD again, error 3b. Will replace with the other module and check back.

    Sounds like a good plan. You may also want to check the other slots to be sure.

    Back to the OEM module. Let's see how she handles.
