Minecraft fails to load upon hitting the "play" button

Minecraft stops loading after about a 90% boot up, or sometimes doesn't load at all. Upon reading game log after having to force quit, the log tells me that the "process crashed" with the exit codes sometimes switching between 1 and -805306369. I've tried reinstalling Java, Minecraft, and updating my graphics driver but nothing seems to be working. 

Upon further examination, when i go to task manager, it says there are 3 minecraft launchers open, which I'm assuming is the most likely cause of the issue. Please not that I can't simply end the task because upon startup of the launcher, all the extra launcher will boot up as well.
