When booting up ? It's seems even if I unplug a usb HDD as it's restarting it'll still kill me mouse... It's bizarre. Like I just rebooted and left all my usb HDD's connected and my mouse was fine upong reboot but all my drives are super slow, like I said before it's like it down to usb 1.1 . It's either it freezes or the usb devices are slow. But if they are all unplugged except for the keyboard and mouse it's no problems... mest up
