Normally when i turned my pc off, i clicked the button, the windows started booting down, the screen goes into sleep mode and the pc turns off a couple of seconds after. Now when i click the Windows' turn off button, the screen goes into sleep mode but the pc does not turn off because as soon as i move the mouse or press a key, the screen comes back on, on the windows login screen. This problem started as soon as i installed a cracked program, since i don't have the money to buy it right now. I use Windows 10 and my pc have an I7 6700k, 16gb ram ddr4, hd 6870 and a Corsair CX750W.
