Hello! I face the problem with my hard drive. It has begun to clicking. When I boot computer for some time I cant hear anything and after that I can hear clicking from hard drive. I am afraid that I could lost all of my files and programs, so I have started to backup them. Do you know what provoked this? Thanks!
I will start with benign cause: maybe your virtual memory running low, so your hard drive tries to perform numerous virtual memory. You will solve this problem if you buy more RAM. Causes could be: bad sector, head crashes and mechanical faults. These problems you wont be able to solve on your own. You have to find a good skilled craftsman.
