I had quite a scare yesterday. My work computer started crashing but it never happened consistently. I was truly frightened that all of my data might be lost. Sometimes the screen would lock up, other times there would be no signal from the computer to the screen at all. A couple of times the computer completely shut off without any warning.
Our computer guy, Danny, worked on the computer all morning and it seemed as though the processor just didn't have a good connection to the motherboard. I hope that's all that was wrong with it. It seems to be working fine now.
