Hi everyone, I have a rather large issue with my PC and Xbox 360 regarding Internet connection sharing. My 360 connects to my router via my PC's connection to the router. In the last 24 hours my PC has crashed/locked up completely 5 times disconnecting me from Live and rendering my PC un-usable until I restart with the power button. Any ideas as to what could cause a complete PC lock up when I'm using my 360 on live? Windows does tell me there is an ip conflict but this has never caused lock ups before. Please help me!
