The first thing to really do is to know your computer well. I am going to stress this since this will help a lot in the early detection of problems. If you don't know what is "normal" for your PC, then you won't know what is "abnormal". Laughing

How to do this? Well, try to examine the internals of your PC (don't be scared to experiment at this point, just be logical and just use common sense when using your PC). An easy way is to press "CTRL-ALT-DEL" on your PC if you are using Windows XP or NT. For windows 95/98 users, it's similar but be sure to press that combination only once or else your computer is going to restart itself. A popup screen will appear where you can select "Task Manager...". (If you don't know what CTRL-ALT-DEL is, then just right click on any blank space on the taskbar.. the bar with the start button on it, and select "Task Manager" from the menu that appears).
