break vs. become broken

[jokaec1]

For example,
1) When this computer breaks next time, I won't repair it and will buy a new one.
2) When this computer becomes broken next time, I won't repair it and will buy a new one.

Are those two sentences both correct? If so, which one is more common? Thank you!

Once again, you can't start a question with "For example". Either you need something before it, or you should just leave it out.

The sentences are both correct.

Would 'breaks down' be more common?

you can't start a question with "For example".

I think the OP can start a post with 'The following are my examples/questions', but I am not a teacher.

 

[Raymott]

No, not without saying what they are examples of. Of course, you can start that way, but you immediately proclaim that you are not a native speaker. You will not see that from a native speaker.
You can say, "The following are my questions:" But a question isn't an example.

"For example" means "Here is an example/some examples of what I've just been talking about".

When this computer becomes broken next time

That sounds unnatural to me.
I would use "breaks" or "breaks down" instead of "becomes broken" in that context.

 

[Matthew Wai]

I think 'this computer fails' is also understandable, but I am not a teacher.

... you immediately proclaim that you are not a native speaker.

All people know I am not whether I proclaim it or not.

You don't give examples out of the blue.
You normally give examples following something that you have stated, for example, a rule of grammar, to explain it more clearly.

What is "understandable" is not necessarily what is correct.

 

[Matthew Wai]

I think you can simply ignore any posts you don't like, but I am not a teacher.

I'm sure Ted's post was in answer to the first post, which gives examples out of the blue. ;-)
