When I startup the computer and I insert my credentials, press login, the Welcome screen appears and after that I get the black screen. I have to wait about 10 minutes and then I have to press a button and my desktop appears.
Now I have noticed, that when I unplug my network cable, I don't get the black screen. Everything is working just fine and I plug the network cable back in when my desktop is visible.
Does anyone has an idea what the cause can be?
I am running a 32 bit version on a 32 bit system and have the windows 7 ultimate edition installed.
