Where could I find a site for basic questions about computer
architecture that's not too technical?

Hi infogamer, 

Probably your best bet is HowStuffWorks.com.  Their computer page is
here: http://computer.howstuffworks.com/ and has all sorts of good
information about various computer hardware.  Some good articles that
you might find useful there are:

How Microprocessors Work: http://computer.howstuffworks.com/microprocessor.htm

How Motherboards Work: http://computer.howstuffworks.com/motherboard.htm

How PCI Works: http://computer.howstuffworks.com/pci.htm

How Quantum Computers Will Work:
http://computer.howstuffworks.com/quantum-computer.htm

Another basic introduction to computer hardware is from FactMonster. 
It gives you an outline of the basic components of computers:

And finally, you might be interested in this site:
http://kosmoi.com/Computer/Hardware/ which is a little more technical
than the others, but still not too complex.

Hope this helps,
