Whoa! The "Blue Screen of Death."

It is a good idea to create a system restore date immediately before installing a new program. That way, you can return to a working computer if the installation messes up.

With that said, here is information on the "Blue Screen"

Blue Screen of Death
The Blue Screen of Death (sometimes called "bluescreen", "stop error" or just abbreviated as "BSOD") is the popular name for the screen displayed by Microsoft's Windows operating system when it cannot recover from, or is in danger of being unable to recover from, a system error (the Microsoft term is Stop error). There are two Windows error screens that are both referred to as the blue screen of death, with one (Windows NT 4/2000/XP/Vista) being significantly more serious than the other (Windows 9x). There are several causes of the blue screen popping up. It can be a poorly-written device driver, bad memory, damaged registry or usage of incompatible versions of DLLs (see more on the "Types of blue screens" section).

The blue screen of death in one form or another has been present in all Windows operating systems since Windows version 3.1. It is the successor of the less well-known black screen of death that occurs in OS/2 as well as MS-DOS[1]. In early builds of Windows Vista it was complemented with a red screen of death, used for boot loader errors.

Abbreviated BSOD, an error that can appear on computers running in a Windows environment. This includes even the earliest versions of Windows, such as Windows 3.0 and 3.1, and still occurs in later versions such as Microsoft Windows 95, Windows 98, Windows NT, and Windows 2000. Jokingly called the blue screen of death because when the error occurs, the screen turns blue, and the computer almost always freezes and requires rebooting.
