I'm not sure it's the heat that did or just the age of my computer but when I came in this morning it would not reload or get beyond initial start setup screen. It informed me that some critical system file was missing, where it went I do not know, and that it couldn't be found. After four hours of rebuilding and trying to get my machine back to where it was yesterday with a recovery effort I'm close but because I had to start from scratch, and this is the computer I work from each day to pay the bills I had to make sure it was working come punch in time. So no show today. Luckily all my important files are saved on the server which is backed up daily. Make a back up today of your important stuff. This is a good reminder.
