#1-TuffTEST-Lite is the first PC diagnostic software product that can automatically test the major hardware components of any Intel-based, or compatible, desktop PC

#1-TuffTEST-Lite is specifically designed for use by PC end-users and less experienced PC support/service people. The powerful and comprehensive tests that comprise #1-TuffTEST-Lite are derived from #1-TuffTEST-Pro, our industry-leading, professional-level diagnostic software product.

#1-TuffTEST-Lite is a "Stand-Alone" diagnostic program that has its own proprietary self-booting operating system. Simply turn the target PC off, insert the #1-TuffTEST-Lite Program Diskette into Drive A, turn the target PC on, and #1-TuffTEST-Lite will boot and take complete control of the target PC. This "Stand-Alone" advantage allows #1-TuffTEST-Lite to operate directly on the PC's hardware without interference from the target system's native operating system. Thus precise and highly reliable test results are consistently achieved.
