The dictionary says 'problem' is countable not both. But can I make it uncountable?

Are these correct? If not, why?
1. I have computer problem. (Can 'problem' be uncountable here or do I need an uncountable determiner? Like this:
2. I have some computer problem. (Why do I need to have 'some' here? There's no way this sentence is correct without it?)

3. I have a weird computer problem.

4. I have weird computer problem.

5. I have computer problem. (If this is incorrect, why? Google has 73,000 results!)
6. I have some computer problem.

7. I have problem. (Is this correct? Can I make 'problem' uncountable like that? If not, why? If I could, that would not be grammatical right?)
8. I have some problem.

9. Some street don't look very clean. (Can I make ‘street’ uncountable? If not, why?)


11. I have stomach ache. (Is this incorrect? Why? I can't make 'ache' uncountable?)
12. I have a stomach ache. (Why do I need 'a' here?)
