I am trying to plug my pc into my tv, it's been working right until I accodentally turned off my pc while booting up a game...

What exactly is "tried everything"? If you tried everything there is nothing left to try.

You may have lost the setting on your PC for the TV. Check your video control panel to see if you need to reset the resolution of the TV as your second display. If it is not compatible with the TV you won't get a picture.
