Hi, I have a really weird problem. My pc seems t randomly crash on network activity. For example, I have a bluetooth network setup for my pda connecting to pc. When I turn off my pda after being connected to the network, my pc will just shut off immediately and restart, without any error messages. It is also the same for my xbox connection. I had my pc on, then turned on ym xbox and started to connect to live. The network cable is always left plugged in. when i tried to connect, my pc crashed again. I left my xbox on and when my pc restarted I connected ok. But when I finished and turned off my xbox the same thing happened. It doesnt do anything else at any other time, just on connection/disconnection from network, and randomly. When i DO connect I can stay connected, copy files etc fine, then im afraid of disconnecting again in case this happens. LOL. What could be wrong? Its not always been a problem. I DID have a network bridge auto-configured by windows so my bluetooth and xbox network could both share internet through my adsl connection. i have disabled this to check if it could be the cause, hat do you think?
