Well you have two options.
A) Go to NHL.com and subscribe to NHL Gamecenter Live. It costs money but you will be able to watch most games on your computer (unless they are televised on NBCSN or the NHL channel)
B) This one is more risky. Go to nhl-stream.com. This website does broadcast all NHL games, but every time you watch a video, you have to exit out of a bunch of pop-ups. I don't recommend this one because you might get a virus, but if you don't want to pay money, this is your best bet.
