I hated being without my PC and was pretty grumpy these past couple of weeks. I'm going go try to learn more about the hardware side of PC's so maybe I can do some repairs myself.
Most of it isn't too hard. Biggest thing is grounding. I've replaced, A drives, Roms, hard drives. The booklets that come with your computer generally walk you through pretty well. And you can always pop a thread up before you do anything to find out if there is anything to watch for, for whatever it is you are going to do. There are lots of knowledgeable FReepers around to offer what they know.
