if i try to press f1 or esc the beeping stop the screen is just black after a few sec it will start up. but after 5 or 10 minutes stuff does not work normally. because whenever i click something like an icon or a file folder it wont open its content instead it will open the properties of that folder. and sometimes also if i want to click a folder to open it the next folder will open. i have not installed anything new in laptop. could it be virus?
