Mouse cursor sometimes not responding
Hi guys, I'm new here.
Earlier today I started experiencing some really weird issues with my mouse cursor. I'm not sure how to explain it, but at times I would see the cursor move but I wouldn't be able to click on anything. If fact, if i clicked something that was selected and open (such as firefox), it would go out as if you clicked on the desktop. Sometimes only the taskbar and top part would be not accessible, sometimes only the middle, and sometimes only Steam would work for some reason. I have to close things using CTRL ALT DEL, task manager and my arrow keys to close things. And I don't think its my hardware cos I have an Alienware. Please tell me you can help.
