Hi, check if your HD is working at that time..! Usually, that's the problem or the Find Fast feature.. <br><br>Solution: Defrag..! of your HD has a problem. or Format..!<br><br>It can be different thing but you must know that when it does that, it's because, there's a hardware device that is working and taking time from the CPU.<br><br>Of course, check if you have a valid driver for your O/S and mouse..<br><br>Ben_Cool
