Can mineral oil result to the rusting of computer components?

Unlikely unless it has a high level of acidity.

Some mineral oils (if you get them on the electronic components) can adversely effect the components ... so I strongly recommend you clean any oil you got inside the PC off.

Use some cotton wool buds and a light solvent to remove the oil.

Does this help answer your question?

I realise your English is a bit rusty so please clarify your request a bit further.
