unstyled 404 page

On my pc I have xampp running, installed wordpress and have the default template which I am customizing. Everything was going swell, pages displaying correctly, publishing content from the wp admin panel, then all of a sudden I started getting 404 errors in my admin panel? The admin panel becomes inactive and any link I click on the interface (publish,edit post, etc.) sends me to an unstyled page from my site with a 404 error?

Viewing my site locally the links work, the content is there, but no styles are present? Very confused? Any ideas?

<update> I actually, uninstalled xampp, reinstalled xampp, wordpress and started over and the same problem occurred.
