When I use computer, sometimes it has been freezing. What I said, for example, I use notepad++ opened files changing automatically without my control.
Also, when I use firefox or on the desktop; the cursor freezed about 30 seconds.
In my opinion, it is a hardware problem because I've formatted on my pc at least 1-2 times.
In addition, when I click ctrl+alt+del or alt+tab, it is fixed temprorarily.
Thanks for suggestions.
It is an example (When I clicked, It is not responded. It is not normal, everytime it is like it on my pc.)
