What is the Mac doing?

Throughout the whole process, my group has faced many of problems to do with our Mac working efficiently. To start with we faced problems such as the laptop just not working properly it kept shutting down occassionally, then iMovie was playing up, when were editing our clips from our filming they would be corrupt when it come to play back and it would just switch to a black screen, eventually we thought we had overcome this but then we had saved the video and opened it up when we returned to it the same problem was just occuring again, and this repeated to happen all of the time but with different clips. The next problem to occur was one when we had started our video editing again to try and overcome the last problem, and then in an unnexpected event the power cable got pulled out of our laptop meaning that the whole machine shut down because out laptop wouldnt not work without the cable as the battery was fried. In the end we decided that we could upload our video to YouTube after editing it all but before saving it, it took forever to do and then once we had done it we watched it back and the problems had occured again, and the resolution and quality of the video was considerably less than what it was on the machine its self.
