Hi This sounds like a problem with static electricity. Your body is building up an electrical charge and when you touch the mouse it is discharging through your computer, causing it to re boot. THIS IS HARMING YOUR COMPUTER. Every static discharge can damage the chip or other parts of your computer, it may not cause it to fail immediately but you may notice a drop in performance. The causes of static build up are: low humidity (not much you can do about that), friction between different materials ie: wool and nylon, for example if you have a woolen carpet and your chair has nylon rollers, or you wear sneakers with plastic soles. Or if you wear wool based clothes and your chair has a nylon cover, etc etc What you can do to prevent this in the future: Always touch something metal that is earthed before you touch your mouse. The static discharge will go to earth via the metal (eg a tap or earthed metal appliance, a metal doorframe in a metal framed building). you can get special anti static pads that you put under your chair to stop the static buildup, and I think you can get an earthing pad to touch in order to discharge the static.... the other listers might like to coment on that as i'm not sure. hope this helps Leigh Jennings [log in to unmask] >Subject: Re-Boot > > >Hellow Friends >I am facing a strange problem.
