Good afternoon. I am sorry for disturbing, but i really need your help. I am experiecing problems which i don't like, but who likes problems? I don't think it is common. I am running a 64-bit version of windows 7(seven). Here it is: I just right click on computer properties. It just doesn't respond. I know I can go to control panel and select system. That works, fortunately, but I really need to know what causes this. I looked so much on the internet, I tried to find sth, but it is hard for me. I don't know, so that's why I am asking for your help. Thank you in advance!
