turn it off and on

[bragandbounce]

My colleague was there fixing his PC. He tried several ways but none of them really worked. I said,

Why not turn it off and on to see whether it works?

Is it idiomatic to use "turn it off and on" in this context? Thanks a lot!

Yes.

In that case I would say "restart it" or "reboot" it.

If you mean for him to turn the power off and quickly turn it back on, “turn it off and on” would be OK. But if you mean that he should shut down and restart the computer using the normal commands/menu options, then “reboot it” or “shut (it) down and restart it” would be more idiomatic.
