So out of anger I Just Punched my computer and its not working now

Not to be offensive or anything but next time you get that angry go for a 5 minutes walk and chill out. If you let an inanimate object get you into a state where you start punching things then you may need a bit of life reassessment. Life is too short and getting that stressed just isn't worth it. Go chill and come back to the problem with a clearer mind. Problems no matter how frustrating they are are just challenges to be solved, punching stuff just ends up being expensive one way or another.
