sorry to hear about your case dude! This is why I don't let my friends touch my computer half of them are idiots and don't know how to use a computer the right way so I just lock the computer when they come over I had one friend crash my computer so I loaded his with adware and spyware and viruses which crashed his! since then I haven't talked to him but still, I was pissed at him for crashing my computer!
Well, he didn't do it on purpose. He was sitting on my chair while I was rewiring on my PC (Biiiig cleanup yesterday) and he usually acts it up too, so when he moved a little to far backwards, he accidently kicked the case and the whole bang there was. I was not really happy. But, I will follow root's way and I will save the most out of it.
I tried to drill two screws, but that made him be worse.
