Dr. Hardware
Dr. Hardware ist an independant and critical hardware information software, made for everyone. It will help both power users and beginners to better understand their computer hardware, configuration and performance. It concentrates its efforts on detecting and inquiring the core hardware and the connected devices. Also several relevant information about resources and operating system will be given.
It shows the really relevant 
  information: important hardware data as well as somewhat sophisticated stuff, 
  that can become of interest under certain circumstances, for example when dealing 
  with the customer service. For experts the program also provides the underlying 
  data structures, e.g. dump of the PCI configuration space or of SDRAM modules 
  eeprom.
  Several charts and diagrams visualize data relations, e.g. free vs. used drive 
  capacity or benchmark results.
Despite its apparantly self-explaining user interface and in order to fully benefit from all features, please read the Program Usage help text!
