Here's a link to the Wikipedia article on Message Queuing Service... http://en.wikipedia.org/wiki/Microsoft_Message_Queuing
Just stop it from starting on startup. Go into MSCONFIG (Start, Run, MSCONFIG) and go to the boot tab. Scroll down until you find the boot process that looks like it's the MQS (that's what I'm refering to it as) and just simply uncheck it. Also, while you're still in MSCONFIG take the time to uncheck things that start up on, well, startup, that you don't want to start on startup. And then click restart when it asks you to restart.
I'm not an uber geek, and I'm sort-of not really new to Windows, so hopefully my instructions work. If the don't work, hopefully nothing terribly wrong will happen
If something does go terribly wrong, just press F8 during boot time, and then when press enter on "Start in Safe Mode with System Restore" and then just System Restore away. To a date when this wasn't happening (by this i mean the MSQ problem.)
