I have recently installed windows XP on my pc and now I can't get an internet connection. And also can't use my zip drive. How do I solve this problem?

What kind of internet connection? ie: dial up, broadband, other?
And some details of your zip drive, ie: type of interface, brand, model, etc.

Also look in Device Manager and give us a report from there detailing flagged devices.

You gave us nothing to work with.
