hello there, i was working on pc when noticed that the cmd prompt window run itself for less than 2 seconds then disappeared. later on (next day) when i restarted my computer it will start as usual then loading the desktop, icons then stops. the mouse can still move on screen but when i try to click on any icons it wont work, and when i pass the mouse over task bar (or on the word "start") it shows a hourglass. checking the task manager shows no cpu activity (0%) and no applications running in the "APLICATION TAP". I tried to run my pc under safe mode. same thing will happen. please help.
