I would like to restore my computer (Windows XP) back to it's factory settings. I am only about 45% sure of how to do this. My computer is very very slow (computer info says I'm at 95% usage for my D: drive and 60% for C:) and I've already been to the malware virus forum a few months ago and that helped a little but right now I just want to erase everything and start fresh. I done everything possible to fix the computer without erasing everything but I have so much junk on my computer I can't remember what is what or what goes with what. So I think the best thing right now is to just start fresh and save the important stuff. If anyone could help me or point me in the right direction that would be great. I have an external hard drive to back up my stuff and I believe I still have the disks that came with the computer but I'm not sure how to use them.
