BleepingComputer.com: Won't Connect To The Internet

Installed win xp pro on my computer and now it won't connect to the internet. Bought it at a yard sale and it worked fine. It had win xp home on it. Daughter clicked on a security warning and it turned out to be a virus. Well, since it was a used computer it had a lot of stuff on it I didn't want or need so I installed win xp pro and now I can't figure out how to get the dsl to connect to the internet. I've tried the new connection wizard and it hasn't worked and the cd I got from the service provider Omnilec doesn't seem to help either. Not sure what info is needed to get some help with this. If someone could shed some light on this I'd be very grateful.

what type of connection have you subscribed? usually it ISP Provides POPoe connection which you will make a dialer using a connection wizard.

Did you do a full install,with format?
What type of Win Xp CD do you have. Full retail or OEM?
was this OS disc installed on another PC that is still running?

Thanks for trying to help out. My puter died right after i posted. Now I'm trying to figure out which laptop I want. that's way harder than anything I've ever had to fix on any computer. But, A lot more fun.
