Strange dots on the MBP 2010 17" screen

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?

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?
