Can somebody give me a completely free, NO TRIAL, good, non-freezing video making software?

Im sick and tired of windows freezing and junk. Its a piece of crap. I need a good software, with NO 30 DAY TRIALS. One that is free to everything. FREE, NO CREDIT CARDS, FREE. One i can import videos too, mix um up, cut some audio, then save and put it on youtube. If not then this "thing" does not exist therefor i am asking for the impossible. Can anybody help a brother out? :)
