Acer am 5630-u5202a boots to Microsoft green bar

This may have happened after an update where a driver was updated that microsoft recommended but was the wrong driver   turn off automatically download and install updates   choose your updates wisely   now to fix that driver either try to roll back the driver   if you can figure out which one it was  even if you have to go to safe mode to do it    or try system restore  to locate system restore choose start/help and support  search for system restore
