Question Only one window is workin at a time.

[Shantrex]

Hi, there is something wrong with my computer but idk how to explain it. Its like only one window i working at a time and i cant use the taskbar or anything else. So when i ALT+TAB to another window nothing is workin. I can move the mouse around but when i hover over for example the "x" button nothing is happening. its like it wont detect my mouse. and i cant click anything. sometimes nothing is working and sometimes only one window is working. and when i use the windows key to open the small windows tab to turn off my pc nothing is working there either. When i hover my mouse over the of button its like it detects it but i cant turn off.

Don't know if anybody understand the problem or even understand the explanation, but hopefully some one does and can help me.

Thanks in advance.
