I own a Dell Inspiron 1720 and have only had it for a couple of years. Last night my laptop would not start up. It would complete initial start-up, but would then ask me to start normally or through fixing the current problems... Still didn't work. I eventually ran a diagnostic test and returned the error code: 2000-0142 (or PSA+ 2000-0142 according to Dell's website), Drive Self Test Failed. Status Byte = 79. Any suggestions??? And thank you.
