What are possible triggers to begin the collapse of an interstellar gas cloud?

A common trigger would be a nearby nova or supernova. Note that it would not need to collapse the entire nebula; just creating a spot of critical density would cause a protostar to form.

When is a star formed?
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
Where does a cycle of a star begin?
Stars usually begin their lives in stellar nurseries: (relatively) dense clouds of interstellar gases. Critical densities may be achieved when nearby stars go nova, at which time pockets in the nebula collapse under their own weight to form a protostar. If the mass of the protostar is sufficient, further gravitational collapse will cause the temperature and pressure in the core to rise to the point where hydrogen starts to fuse. At that point, a star is born.

What caused the interstellar cloud to collapse?
Nebulae are massive collections of gas and dust that usually are very cool around 5-30 kelvin. These nebulae are the remains of dead stars that have long died and have had enough time to cool themselves from the original energy release of the nova or supernova that created them. As the nebula cools the particles begin to slow down and once cool enough gravity will begin to collapse the nebulae and form what is known as a protostar. This is the birth of stars, and is essential for star formation.
Can red supergiants become black holes?
Red super-giants form when stars of more than ten solar masses begin to burn their helium. Eventually such a star will burn all of possible fuels and go into gravitational collapse, resulting in a super-nova. If the mass left over from this collapse is large enough (a remnant of three to five solar masses), the remnant will collapse into a black hole.
When did the Mayan civilization begin and end?
it started in 400BC and began to collapse in 900AD
How is star formation related to spiral arms?
As interstellar clouds approach the spiral arm region it helps them to begin the collapsing process and eventually form a star.
Write it Down?
Many people who suffer from migraines also have triggers which contribute to the headaches. When exposed to these triggers, a migraine can start instantly, or shortly following exposure. You can get migraine relief by figuring out your triggers using a headache journal. Write down all food eaten that day and how you feel after. If you have any food triggers, you will begin to see a pattern, such as getting a migraine shortly after drinking alcohol or eating chocolate.

Where the star came from?
Scientists believe that the Sun and our solar system formed at nearly the same time out of the solar nebula - an enriched interstellar gas and dust cloud that existed where our solar system now lives. The theorized order of events for the birth of our Sun is similar to what we see in newly forming stars today. Compression from nearby disturbances causes the interstellar medium to collapse. Small clumps of gas and dust break away from the larger cloud. These denser knots have gravity and begin to gather other gas and dust around them. Temperatures begin to rise due to the further increase in gravity from material in the collapsing gas cloud. The center of this fragmented gas cloud evolves quickly (over the next 100,000 years) to form a protostar and once pressure and temperatures reach a peak, nuclear fusion begins. for more info check related link
