Recovering documents from computer onto new hard drive

My computer recently froze in the middle of watching a TV, which resulted in the gray screen of death and resulting in my hard drive crashing and getting a replacement. After getting home and starting from scratch again, I happened to search a few words in Spotlight and up popped results in documents that had been saved on my past hard drive. I don't have my Microsoft CDs with me to reinstall Word, so the documents only open up in TextEdit, but I'm trying to figure out how to get to those documents? And where are they saved???
