So I sorta had this issue before. I installed connectify, a program, and after right away like last time or the next day, when I launched my pc it brings me to the login page and right away says incorrect user or pass, then I press ok type in my right password, it spins for a little bit And then my screen goes black. Sound inside the pc like fans and stuff doesn’t stop. Same issue when I load into safe mode
