i got this error day before yesterday. i came home to find that my computer restarted itself for some reason. i dont know what would have caused that but i guess during the reboot is when i got the error. it said "non-system disk error. Replace and press any key to continue" there was not anything in any of the drives. so i turned off the box and then back on, same problem.
so i turned it off and left it that way until last night and though i would give it one more try and it fired right up. what gives??
