PLEASE HELP so I've been using Windows 10 since release now with little or no problems. I was playing yano old game (gta San Andreas) when the game crashed. I pressed the reset button on the front of my pc to restart the pc. Now, I can log into Windows fine but clicking anywhere does nothing. I can do nothing with the mouse at all. Also, when I try to type sfc into the console it says I am not an administrator. Cam anybody please help?
