The OS is still just on the hard drive. Where do you think 'Brick' came from? The piece of electronics is unrecoverable by anyone trying anything, so must have parts replaced. Make sure you understand that that includes people who know what they're doing. Buying a new PC because the cost is about the same as repairing it for fools is an abomination of logic. That a fool has to buy a new PC because his old one is unrecoverable to him does not lead to the conclusion that the old one was bricked. He's just a fool.
