Hello, yesterday night a strange thing happened to me, and no matter how many restarts and stress discharge I did, nothing worked. The computer turns on and everything is normal, puts in the password and the desktop only rises when it's empty and the mouse shows as if it was thinking. I waited a minute 10, waited all night nothing changed. Furthermore, except cntl + alt + del nothing works (nor does it open anything but that way you can shut down the computer or exit the user) winkey + r / winey + p or right key on screen also does nothing, start boot. Specs: Intel i7 920 Processor - gigabyte ga-x85a-ud3r Ram-12 Giga (scum of some things ..) Video Card - gtx 760 Update: Problem in my hard disk operating system, what can I do with it? Thank you!!!!!
