Hi teachers,

1) I am just finished using computer/PC. Correct and don't we need to use an article?

2) I am just finished watching TV. Correct and don't we need to use an article?

Many thanks in advance.

Just as you have used it above. I don't understand the connection between your latest question and your first one, however.
