Come across place that's verging on the ridiculous and PC (8)

I believe the answer is:

computer

I'm a little stuck... Click here to teach me more about this clue!

'the ridiculous and pc' is the definition.
I can't judge whether this defines the answer.

'come across place that's verging' is the wordplay.
'across' indicates putting letters inside.
'place' becomes 'put' (synonyms).
'that's verging' becomes 'r' (I am not sure about this - if you are sure you should believe this answer much more).
'come' going around 'put' is 'compute'.
'compute'+'r'='COMPUTER'

'on' is the link.

Can you help me to learn more?
