Why does a link in my navigation bar suddenly align to the left?

[Neuto]

Hello I am new to web designing and I recently created a website.
I am having trouble with the navigation bar.
For some reason when I click on my Welcome page the links appear fine...however when I click on my resources page the "Sign up/In" link is now located under the home link.

Welcome
Resource

I thought I would be able to eliminate this problem and others by doing a frameset only when I tested the frameset I couldn't get rid of the borders.
Also I would like the bottom links to be well at the very bottom. I am not sure how to do this.

You can find the code for each page by clicking on view source.

Please help.

I answered my own question.
I just had the browser window smaller.
This really feels like a "did you check if the machine is on?" moments
