My cursor starts blinking. I cannot click on anything. Also, sometimes the cursor goes up to the far right upper corner of the screen and stays there. It won't move. The only thing I can do for both problems is unplug my computer and restart it. I have had to unplug my computer 5 times today and once it came back on with the blinking cursor and wouldn't go anywhere. I work from home and it is driving me crazy. I have tried using 2 different wireless mouses. I have tried using a plug in mouse. Nothing works. My computer guy couldn't fix it. HELP ME PLEASE!
