 My question is can I put in a PC133 card or will it not run?

Answer : Problem: PC133 on a 100 MHZ computer

If you are talking about PC133 RAM, it depends on the manufacturer.  Kingston is the only one that I know of that still produces PC100 compatible PC133 sticks.  If you put a PC133 stick in a PC100 slot it will run like a PC100, same for the 66.  I suggest just buying some used PC100 sticks off ebay or at a local computer repair shop.  If you try to get something new to work in that computer, you might as well buy a new Dell for $500.
