Stress testing, in general, should put computer hardware under exaggerated levels of stress in order to ensure stability when used in a normal environment. These can include extremes of workload, type of task, memory use, thermal load (heat), clock speed, or voltages. Memory and CPU are two components that are commonly stress tested in this way.
Memory module testers can be broadly categorized into two types, hardware memory testers and software diagnostic programs that run in a PC environment. Hardware memory testers have more sophisticated and comprehensive test features built into the tester as compared to software diagnostic testing programs.
Inquisitor is a software suite used for hardware diagnostics, stress testing, certification and benchmarking platform. It is available in three formats: It is available in three formats: Standalone – As a package to be installed into existing Linux installation; such practice is somewhat limited in available tests.
In computing, stress testing (sometimes called torture testing) can be applied to either hardware or software. It is used to determine the maximum capability of a computer system and is often used for purposes such as scaling for production use and ensuring reliability and stability. [ 1 ]
During the POST, the BIOS must integrate multiple competing, changing, and even mutually exclusive standards and initiatives for the matrix of hardware and operating systems the PC is expected to support, although at most only simple memory tests and the setup screen are displayed. The principal duties of the main BIOS during POST include:
MemTest86 and Memtest86+ are memory test software programs designed to test and stress test an x86 architecture computer's random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors. [6]

The scheduler wakes the computer from sleep, runs all the scheduled tasks and then puts the computer back to sleep. During this weekly task, WinSAT runs long enough to detect if there have been any hardware changes. If so, then the tests are run again. If not, then WinSAT simply ends as the existing scores must be valid.
