Hey, I also have a Dell Inspiron 1100. I think that we are in the same boat that our computers are pretty well outdated. I have looked around, and unfortunately RAM seems to be the only thing that is upgradeable. Anything else seems to be such a pain and cost soooo much that we are better off to just buy a new PC. I'm planning to work a lot this summer, save the money, and build my own PC. If somebody out there does know how to cheaply and easily upgrade Dell Inspirons, LET ME KNOW (private message please) !!!!! I've got a 2.30 GHz Celeron and 640 MB of RAM. However, integrated Intel graphics just aren't cutting it.
