Windows XP fires up, and the user icon is displayed. Then, when I
click on the icon it says it is loading my personal settings, but
then I get the blue screen.

Can you still boot into Windows' safe mode and then login okay?

Yes, I can boot into safe mode (I had
forgotten about that). In safe mode, I
successfully restored to about a week before
this happened, but no change.

I also checked my screen resolution, as that
seemed to be what started this. However, in
safe mode this is only 800 by 600 pixels,
and cannot be changed.

In safe mode, how do I change the screen
resolution when not in safe mode?

If safe mode works okay, next is to disable all startup items and
reboot into normal mode. In safe mode, run msconfig.exe and disable
all items under the Startup tab. Then reboot into normal mode.
