Since

What's the correct form to ask?
1# Since when do you know to work with computers?
2# Since when have you known to work with computers?

I think that 2 is grammatically correct,though, sounds odd. 1 sounds better but seems to be incorrect grammatically.
Thanks

I would say 'Since when have you known how to work with computers?', M.

Or, with a slight change of meaning: 'How long have you worked with computers?'

Or, jeeringly: 'Since when have you known anything about working with computers?'

MrP
