Hello everyone. I've been pretty long with the phenomenon I'll explain. I do not remember when it started. This is a standard desktop computer with an I5-6500 processor, a 16GB Kingston RAM, a Windows 10 operating system, a crucial mx500 SSD and an additional storage (standard mechanical of the Seagate Barcode). The computer is super fast for me and I am very happy with it. The phenomenon, when the computer is left unused when it is running, and the windows are open, after a period of a few minutes or a little longer (I find it difficult to measure), I touch the mouse to return to tasks or windows, all windows seem to pop up, as if paralyzed, some resize from maximum to minimum . Then all the windows should be arranged in the normal position. As if the computer was in "Paris" and he seems to be coming to life. So tired of working with the computer. Does anyone have an idea or do you know of such a glitch. Thank you very much for all the answers.
