Suddenly my mouse stopped working. When I double click on any document it does not open up. I tried clicking the same number of time but does not looks to be working well. I had checked the mouse settings also, they look appropriate. First I was getting issue with freezing.The system freezes in between and then starts working back to normal after few seconds. I am nto able to find any option for the same. My cpu usage simply pops up to 100% and when I reboot it goes back to normal.
