BurnInTest allows all the major subsystems of a computer to be simultaneously tested for reliability and stability. BurnInTest will bring intermittent or hidden problems to the surface so that after a successful run the computer can be used with a high level of confidence. BurnInTest can also be used by overclockers to verify system stability at high clock speeds. BurnInTest tests the CPU via mathematical operations and MMX calculations, hard drives, RAM, CD ROMs, sound cards, 2D graphics, 3D graphics, network connection, and printers.

Version 2.2 adds multiple simultaneous disk and network address testing, additional error logging, support for Windows Me, and more.
