You don't actually say you don't have a Windows Disk, but since you didn't correct foulestroupes's assumption, maybe you don't. You probably needn't worry though - lots of times, instead of giving you a Windows Disk they give you a Restore Disc, which has Windows bundled in with other stuff. For most practical purposes it comes to the same thing.

With such a disc, if all else fails, you it the Restore Disk to put the computer back to the way it was when you bought it, with Windows and various other stuff they might have put on there, such as games, or maybe Internet Explorer. Then you have to reinstall anything you put on later, such as maybe a word processing program such as Word. (And you'd lose any data you had, letters and tunes and all, except that you could save them easily enough preferably on a CD if your computer has a CD writer, or otherwise on some floppies.

Just to restore Internet Explorer, it's a doddle, you just need to get hold of a disc with the program on, and they come free on the cover disc of magazines such as .net, along with lots of other handy stuff, and that just costs a fiver.

One possibility might be there's some problem with the ISP connection, even though it looks OK - it would be worth phoning them up to check that. Quite often the blokes on the helplines are quit re knowledgeable and helpful.

I take it you are using some other computer to get through here?
