I'm referring to a PC Check, or Memtest style program that actually tests the hardware- not a "does my speaker work type" app. I deal with many devices that have inexplicable operating issues that are not resolved by flashing new ROMs, kernels, etc. It would be nice to know if the RAM modules, or CPU are failing. If nothing else to satisfy my curiosity, as well as to avoid any resale headaches.
Any info or suggestions would be greatly appreciated.
