I waited on my computer to finish updating after it rebooted. But instead of coming back to the main screen it is the bad blue screen. What could cause it to kill my computer? Would running out of memory cause it? Is there a simple fix to get it back?

I have roommates that are connecting to my Wifi and slowing down my speed. Is there a way to block them from being able to connect to my Wifi. I need to do this without them knowing I am the one blocking them. Or is there a way to slow down their connection so they will not want to use it?

I am not sure if this is possible. So I thought it would be worth asking before I tried and failed. Can I install Cisco ASDM to install on Macbook Pro? What version of Java do I need? Does anyone have any advice or suggestions for a project like this?
