I am very frustrated. I bought a $200 security system for Microsoft and they said that would do any service. So my screens goes black and I call them and they go into my computer and say that it's a IP address problem and it has to do w/ the network so they want to charge me another $149 I said no ...now my computer will not boot up I put the computer password in and it has a screen that says Lenovo and a ongoing dotted circle and it won't open... do I need to call them back and for $100 get a new Microsoft key ! Help !!
