Hi, I´ve got a problem with my PC- When I want to turn it off, the OS shuts down itself, but the machine keeps running until I shut it down with hard reset. Even the monitor is recieving signal, but the screen is shining black. This problem started to occur, after I installed Elementary OS and updated to the latest kernel and did some fixes in grub. This happens with my Win 7 installation too. If any other info is missing, I´m sorry and feel free to ask me. I really appreciate all the help. Thank you.
