Bobby has Windows 7 Home Edition and he's getting a BSOD. Leo says the blue screen is what happens when something goes terribly wrong and Windows can't go on. There's only two ways to get a blue screen these days: 1) A hardware issue failure, or 2) A Ring Zero failure in software, like a driver issue. Leo recommends updating all his drivers first. That's the easiest thing to troubleshoot. There's a wireless driver that Windows installs automatically that causes the crash, so that could be the culprit.
