What other hardware, internal and external?
OS? Fully updated?
This machine freezes randomly
Freeze vs Crash - very different things.
By "freeze" you mean everything stops and even the mouse cursor is
immobile? IOW, you're NOT seeing the panic screen (a full system
CRASH) and there are no application crash logs?
Does disconnecting the keyboard and mouse, then reconnecting restore
functionality?
What apps are running?
What are the last things to go into the system.log before the freeze?
so, I replaced the original 350Mhz processor with a 450Mhz from a
similar machine.
What made you think the processor was at fault?
Does the system BONG normally when booted?
Have you tried reseating the RAM, HD interfaces, etc?
I checked the crash logs but couldn't decipher.
What crash logs? Freezes don't produce crash logs.
Aug 11 13:57:33 localhost kernel[0]: ROM ndrv for ATY,Rage128Ps is

leads me to believe the driver for the video board is out-dated. Is
this the case?
No. Ignore that message. It's informational and not related.
I searched the web for a Mac driver to no avail. I observed the last
crash occurred when I had a number of windows open and was moving a
page.
Ok. Now you're talking about crashes not freezes... Exactly what crashed?
Also, a page or file opening, appears jerky - like a strobing or
step frame rather than smooth. My monitor is a Viewsonic 19" @
1680x1050 59.9Hz.
Poor video performance such as you describe is simply the video card
being unable to keep up with the demands. The card you have is
probably targeted to smaller / lower resolution displays.
Does the jerkyness go away if you lower the display resolution?
Try changing the refresh frequency, to see if the strobing lessens.

Don't ever plug in a monitor bigger than 17" in a card that is less

might freeze.
Baloney. A bogged GPU does not a freeze cause.
