Hello, I have Windows 7 for about a year now and I really didn't have any problems up until a few months ago. My mouse pointer would start refreshing/flickering every 5 minutes or so and it would slow down anything I was watching or playing at the time. It doesn't really bother me when I watch movies because I can just shake the mouse and it would stop but when I play games I can't do anything about it and so I can't really play any games. I asked my repair man, he also has Windows 7 but he didn't know how to fix it. Is there a way to fix this problem?
