I'm sure the new computer plays both types dvd & cd.

Just ask the person at the store to make sure it is a cd and not a dvd.
but usually they use cd for those sort of things.

- your new puter w/ win 7 (correct??) might recognize a lot of that stuff without needing any cd at all. I haven't even looked at much about win 7 , so not much help in that area.

and if the cd won't play just go online to the manufacturer/brand name of whatever you buy and find the drivers or program needed and download /install them. usually in the support section.

The modem/router set up can be easy or tricky, if it is tricky call up the dsl provider.
Verizon & frontier would prefer you just buy the combo router/wifi//modem from them.
they will help you much more if you use their equipment, not as much if you bought your own router.
At least that's what they told me- but they still helped me figure out my problems a few times but it was on their side one time.

I'd suggest looking into the combo and trading up from the modem that you have. You'll get a lot more tech support if trouble arises.
