My Mom has a decent Hp home pc setup that is less than a year old. When I set it up I showed her how to turn the computer on and off and how to do the basics. Every weekend when I go visit I do a little house cleaning with it and make sure she has all the needed updates. Last weekend I noticed that it was running a little sluggish so I decided to defrag the hard drive. It took three hours. It shouldn't have taken that long and it concerned me but I didn't say anything to her. Last night she called me and said that the monitor would not come on nor could she cut the computer off. She said the blue light would not turn off either. BLUE LIGHT! What Blue Light. She replied "you know the blue light on the computer" I then asked her how she is turning the computer off? She replies I just push that button with the blue light on it. I had to power boot the thing. It was froze up harder than granite rock. I didn't have a lot of time to spend on it as I was working but somehow I think I will have to spend some time on it tomorrow when I go visit.
