Hi. I am looking into buying a very compact gaming computer and also for video editing. I have already set up a build and was wondering if the build was any good. And one more thing, which os should i get, windows 8 or windows 7?? Parts list: Cpu: Intel core I7 4770K Cpu cooler: Cooler master...

Hey guys. My friend said he turned his laptop on and it pulled up the black screen and said Hard Drive not found. He hadn't done anything to it according to him but he did remove the hard drive later and "blew on it" (lol) but it didn't help. Any pointers?
