The other night; my desktop computer just gave up and stopped working. It was time for me to get down on my knees and open the CPU. At the very time I opened a toolbox, took a screwdriver and guess what...the required bit was missing. The story does not end here. It took an hour to find out that screwdriver bit. Anyways, I came with a winning smile on my face and was just about to open the CPU...the power went off in the middle of the night! Well holding a torch in one hand or mouth and trying to unscrewing wasn't that a good scene.
