If you were an early adopter of Windows Vista, there’s a pretty good chance you became familiar with one of Vista’s coolest new features: an automatic crash reporting utility that will recommend solutions if and when they become available. Or to put it another way, if you tried running Windows Vista on many machines, there was a good chance your computer crashed. A lot. Even if the manufacturer had slapped a shiny new label proclaiming the computer to be "Vista Capable."

There’s a class action suit working its way through the courts to determine whether Microsoft changed the definition of "capable" to help Intel sell computers chips. But some of the documents released in the case (PDF link) are interesting in their own right. For example, Microsoft has a chart that lists identified causes of Windows Vista crashes during an unspecified period in 2007.

The folks at Ars Technica took it upon themselves to convert that data into the pretty chart you see above. The number one culprit graphics chip maker NVIDIA, a company that had a difficult time updating its graphics drivers for the new operating system. Next up is Microsoft itself, and really there’s no good excuse for that, is there?
