This happened to me on my last computer. When I run the program and I'm in the process of downloading for a few minuites it will just go blue and lock up my computer. I get a message that says DRIVER_IRQL_NOT_LESS_OR_EQUAL Then it also says Physical Memory Dump. I messed around and finally got Azureus to stop giving me blue screens. I don't really know what I did. Now I have built another computer...installed the program again and it's giving me the blue screen again. I'm not sure what to do????
