    Hello, when I woke up the MBP this morning, I noticed some dots near the middle of the screen. After I logged in, they disappeared.

    Such appearances of strange dots have happened a few times over the year but not too often. The location varies. About 1.5 month ago, they showed up on the dock. What are they? Is it a software glitch?

    Not I am aware off. For today's case, I put it to sleep mode and woke it up few hours later. Then, those dots showed up.

    As I recall, they happen randomly at any time.

    The Macbook has the nVidia 330gt gpu? Is it possibly due to a failed c9560 capacitor?

    Yes that GPU. Not sure if it is due to a failed capacitor. If so, is this bad? What will happen next?

    I'm not sure if it is a failed capacitor.

    To test for a capacitor problem, run the Cinebench r15 OpenGL test. If the Macbook passes, it's probably not due to a capacitor issue.

    It should not make it worse. I ran it a few times on my mid-2010 15". It's the test that confirmed I had a failed capacitor.

    The capacitor is a known issueand was also the reason apple had an extended warranty program to deal with the problem. Unfortunately, the warranty program is over.

    I ran the test: 15.53 fps (Ranked 7) for OpenGL and 192cb (Ranked 8) for CPU test. Did not see any fail or error message.
    I am using OS X 10.12.6.

    That's great so it doesn't appear to be related to the nVidia gpu. Unfortunately, troubleshooting the issue becomes more difficult because it could be a ram or hard drive too.

    How likely this is a sign that the computer will fail sooner or later within the next few months?

    Not really sure that anything is our will fail.

    Is it possible to run the Macbook with only 1 stick of ram or use different ram sticks?
