We have got one person in mind and one person only we can sort out all your solutions to your computer crashing in a way that you thought was never possible, the device fits into your machine so that you cannot see it or alter it in any way at all.  Its completly hassle free at all times and works through a hidden menu that only you know how to access.  The kids can't destroy it either anything they download will be removed everytime you reboot unless you want it there.
