I appear to be having Network Card difficulties. In Device Manager NVIDIA nForce Networking Controller has an error code 10 saying it cannot start. I've tried uninstalling the drivers to no avail.
I recently had a corrupted registry which made my computer continously reboot as a result of an lsass.exe error. I fixed this after somce advice which involved a little bit of correcting. It could be possible that these two are related?
Anyway, I have no idea wheer to start diagonosing this problem. I imagine you need some details of my computer which I can get to you when I know what is needed.
