Maintenance such as your monthly canned air on the vents and if the machine has never been cleaned you find yourself going inside to clean off the heat sinks.
There's also malware but at first blush I'd like to think it's just the old canned air work. Those that don't do their own Maintenance often ask questions like what is canned air or how to use. Fortunately those answers are now on the web.

I was getting a presentation out on Microsoft Powerpoint and then the screen stopped, went blue and just completely shut off. This isn't the first time it has happened but I've never given it thought.
However, of lately, its been really frequent and it keeps shutting down at the most inappropriate hours. I've lost assignments because of this. What is happening to my computer? Is this something I can fix or does this mean I need to get a new computer?
