|"My machine is a DEll Celeron"|
Celeron is a processor, not a computer. We need to know the exact model & model number of your Dell. Is it a Dimension, Inspiron, Optiplex, etc? It should be somewhere on the tower. Possibly on the front or a tag/label on the back. For example, here's a Dimension 3100:
Once you find out which model you have, you can find, download & install the proper graphics driver.
Also, you were asked about the "128" you put in your specs. If that's the amount of memory you have, XP is going to run like crap. It needs at least 512MB to preform adequately, 1GB+ to run decently.
