PowerBook - Just weird

For starters Hello! and apologies if some of these questions have been answered, I normally do my own troubleshooting with a little internet research but alas my problems are too many. I recently moved and had to get a new router (Westell 327w) with Bellsouth fastaccess. Oh yeah, Powerbook G4 (about 4 years old) running OS 10.3.9

Now:

- safari, limewire, and software update will not fully load. They will access but not quite get all the way there. (pinwheel)

- the upper right part of the screen (date-and-time), battery power etc. whenever I put the pointer over it.... pinwheel.

- date and time are frozen and when I go to my preferences to change it, there is nothing wrong! Files are stamped correctly, all the settings are correct, still 5 minutes late to work.

- Firefox seems to be the only browser that works, hence the only reason I can post on this forum.

I do not know if this is a setting problem, a router problem, or what. I am just a designer Jim!

If anybody has an answer, or multi-diagnosees? multi-diagnosises? multi-diagnosi? or even a method of GENTLY pulling the hair out just let me know!
