I would still test the RAM that is currently in your machine by replacing it with known good RAM. I wouldn't be surprised if that has been your problem all along. I have seen this before. You can not be sure until you do this.

On another note, I have a question about some files in the /proc/sys/net/core/ directory. After running the tweak test on DSL reports, it explained to me that I need to change the size of my recieve window. Currently 65530 and reccomemdeded to be between 14000-37752 for my connection. So I went in to the files rmem_default and rmem_max and changed the values. (logged in as root, then used vi) When I reboot the machine, the values return to the ones there before I made any changes. Can you tell me why this is, and if it will make a difference in my connection/download speeds?

"/proc" only exists when the system is running. It's not a real filesystem. You can make runtime adjustments in there and even put a command in one of your startup scripts (rc.local):
echo 65535 > /proc/sys/net/core/rmem_default
echo 65535 > /proc/sys/net/core/rmem_max
Better yet, do a "man sysctl" and a "man sysctl.conf" and put your changes in the /etc/sysctl.conf file.
Please install your kernel source and read the /usr/src/linux*/Documentation/networking/ip-sysctl.txt for an explanation of these parameters.
Or you can change the values in the kernel source and rebuild and they'll be perm, but I would not recommend this method (upgrading will reset the default you desire). I would be suspect that reducing this will have the desired effect, but I encourage you to experiment.

Once again VoidMan, thank you. I feel like I should send you a Christmas card. You realize that if you look at some of my earlier posts, it wasn't too long ago that I was asking how to mount my floppy. Obviously, you've been a big help. Of course I'll always have more questions, but at this point I feel guilty asking you anything else. But I would appreciate a picture of your Traxxas truck if you have one.

No problem, and there is a web site dedicated the the truck we have: http://www.t-maxx.com/ which even has some pretty good movies of it in action.
