# Test descriptions |

There are many different hardware component tests built into the software. Each of these tests contains one or more sub-tests designed to exercise different aspects of your computer system. These tests can be run concurrently, with each test having its own window and using its own CPU thread or as individual tests. It is also possible to vary the load mix by increasing or decreasing the duty cycle for a particular test. Each test keeps an error counter, a cycle counter and an operations counter. The significance of each of these counters is detailed with each test. The following tests are currently available. 2D Graphics tests Video adapter memory testing Tests of standard two dimensional graphical functions Monitor EMC testing 3D Graphics test Tests the DirectX 3D graphics system Battery test Test a battery in the computer CPU tests Tests a wide cross section of CPU functionality Disk tests Reading, writing files GPGPU tests Test the General Purpose computing capability of a GPU Memory (RAM) test Tests the Memory in the computer Microphone test Test a microphone in the computer Network test Tests the Network connection Advanced Network Test Optical drive test Tests the CD-ROM, CD burner, DVD-ROM, DVD burner, BD-ROM and optionally the sound card Parallel port test Tests the parallel port connected to the computer Plug-in test Integrate your own test to BurnInTest Printer test Tests the default printer Serial port test Tests the serial ports connected to the computer Sound card test Test wave form, MIDI and MP3 audio play back Tape drive test Tests the tape drive USB port test Tests the USB ports on the computer Video play test Test the playback of different video files Web cam test Test a webcam
