What all did you install? What version did you use? What are your computer specs. What software did you have installed before SP3.x? I used 3.8. I installed the base additions and some other things. My computer specs are NOT sufficent, I just learned. I only have 40MB of Ram. But that's not an issue, I just want it to go back to how it was. My parents won't let me buy a floppy drive for it.
