Ok, I've got a big update for you.
I went out and bought some upgrades for this computer so my son could run the game Spore on it. Here's what I got; 2 GB of DDR2 SDRAM and an Nvidia Geforce 9500 GT 1 GB card.
It took some time and few phone calls for me to get everything up and running, but now this machine is blazingly fast and the screen flicker is gone!
I'm posting a new log to let you take a gander at and see if all is well. By the way, my son loaded up Spore and showed me it running at 52 frames per second. I guess thats good right? All I know is the flicker is gone.

Just so you know also; If not for you fine folks here at this site I never would've thought about upgrading this machine. I definitely would never have taken the case off and added stuff to it!

I had visions of destruction with my big meat hook hands mucking around in there. But you folks gave me the confidence to do it and have showed me there's nothing to fear. I salute you.
