I am looking for a hardware diagnostic solution where I would be able boot from a USB thumb drive and run from the thumb drive the diag software that would detect and digagnose all hardward from the Motherboard,RAM,Hard Drives, serial ports, Video, Ethernet ports, etc. The diagnostics would generally test for functionality, regardless of what OS would be installed on that particular system. These systems generally run Windows XP or BSD (UNIX) but the diagnostic software should not really care what OS is on the system, only that it will boot from the thumb drive and test the system. Is this within the scope of PC-Doctor?
