1) What is the make and model of the computer?
2) When did you buy it? Can you get support from the maker?
3) What do you mean "reset it?" Factory reset, wipe the disk, a button on the motherboard? This could be the source of the problem
4) Please provide the exact message. We can't see the PC from here, so we need a lot of details!

You'll need to re-install the OS. Would recommend backing up your PC in case this happens again. RollBack Rx or Comodo Time Machine should work!
