les problemes: fournir les drivers pour le controleur disque
fournir les drivers pour la carte son

General guidelines
A computer with a base score of 1.0 or 2.0 usually has sufficient performance to do most general computing tasks, such as run office productivity applications and search the Internet. However, a computer with this base score is generally not powerful enough to run Windows Aero, or the advanced multimedia experiences that are available with Windows Vista.

A computer with a base score of 3.0 is able to run Windows Aero and many new features of Windows Vista at a basic level. Some of the new Windows Vista advanced features might not have all of their functionality available. For example, a machine with a base score of 3.0 can display the Windows Vista theme at a resolution of 1280 × 1024, but might struggle to run the theme on multiple monitors. Or, it can play digital TV content but might struggle to play High Definition Television (HDTV) content.

A computer with a base score of 4.0 or 5.0 is able to run all new features of Windows Vista with full functionality, and it is able to support high-end, graphics-intensive experiences, such as multiplayer and 3 D gaming and recording and playback of HDTV content. Computers with a base score of 5.0 were the highest performing computers available when Windows Vista was released.

Usage guidelines
The base score is a good indicator of how your computer will generally perform. Subscores can help you understand your computer's level of performance for specific usage scenarios as follows:

Office productivity. If you use your computer almost exclusively for office productivity, such as word processing, spreadsheets, e mail, and web browsing, then high subscores in the CPU and memory categories are important. Subscores of 2.0 or higher are usually sufficient for the hard disk, desktop graphics, and 3D graphics categories.

Gaming and graphic-intensive programs. If you use your computer for games or programs that are graphic-intensive, such as digital video editing applications or realistic first-person games, then high subscores in the RAM, desktop graphics, and 3D gaming graphics categories are important. Subscores of 3.0 or higher are usually sufficient in the CPU and hard disk categories.

Media Center experience. If you use your computer as a media center for advanced multimedia experiences such as recording HDTV programming, then high subscores in the CPU, hard disk, and desktop graphics categories are important. Subscores of 3.0 or higher are usually sufficient in the memory and 3D graphics categories.
