Definitely this is related to the program which I ran today; "Regcure" and everybody know what it is. Fine, after I restarted PC via start menu, after booting up screen and mouse shows it doesn't do something else. The screen is blank excepting my cursor, which I can move. I would attempt to go in safe mode, but I forgot how to do. And after going to safe mode and it works, what else can I do?
