I have a Toshiba Satellite M105-S3021 with Window XP SP2/3 and it is going ballistic when it wants to. The screen just start moving very rapidly from side to side like something is shaking it. I have to hold the power button down to shut it off. I don't know if it is the touch pad or what. I need to know how to disable the touch pad due I think it happens after I use the touch pad. I went into the Control Panel and Device Management and the Mouse properties but the only thing listed there is: PS/2 Compatible Mouse and HID-Compliant Mouse nothing about the touch pad. Please help
