hi, i am having a problem with windows 7 hanging upon start up, until it finds the network. once it finds the network it is fine until then everything hangs and i hav this green circle over the network symbol in system tray. i have tried doing an upgrade install but it fails and won't start again due to it says it needs to finish the previous session. i either need a fix for this network issue, which also stops me enabling netprofm and any networking services. or a way for me to get rid of the traces of the attempted upgrade so i can try again. i have already tried diskcleanup and have manually deleted any extra files i can see in the c: thanks ally
