Troubleshooting 101 -- at its core -- involves identifying a problem on a computer and using that information to resolve any issue(s) stemming from said problem. While most troubleshooting takes place at the OS level, there will inevitably come a time when the hardware itself will be the cause of a system's instability. Many 3rd-party tools exist to root out hardware trouble, sometimes heuristically, even before the component has failed. But many Mac owners do not know that Apple bakes in a utility specifically to test hardware found in Apple computers of all sizes. There are two utilities, as a matter of fact, and depending on when your device was manufactured, you'll access  Apple Hardware Test  if your computer was manufactured prior to June 2013. If the computer was manufactured after that date, then  Apple Diagnostics  is the utility that will load. They're both very similar in what they accomplish -- a self test of the hardware, complete with scans of internal

Heat problems can often be addressed simply by cleaning out any dust with a can of compressed air and keeping the vents unobstructed. In other instances, however, you may have a bigger problem, such as a broken cooling fan, or a heat sink that needs re-seating. These fixes can sometimes be tackled at home with the right tools and some Googling for tutorials, but if you don't know what you're doing, you might want to take your PC to a professional before trying to open up the chassis yourself. To ferret out memory problems, start by finding out where memory is being used. In the task manager, select the "Processes" tab. You'll then see a list of all the various processes running on the machine at any given moment. Without opening any programs, take a look at the percentage of physical memory being used.

In the early days of the Internet,   storing data   and accessing applications on servers located beyond the walls of our homes and offices was more science fiction than business reality. Users dug the concept, but wouldn't dream of getting real work done with a browser connected to the Internet. For many people, the browser and the computer have since merged into a single entity. These folks no longer buy and install software. Instead, they boot up their computer, launch their favorite browser and then access a number of applications, hosted on servers all over the world. Their data is stored there, too -- out in the cloud, far from the spinning platters of their hard drives. And they're getting serious work done. You can be one of those people, too. You still need a computer, but you don't need to invest in expensive software. Most   cloud   services -- or Web apps, as they're sometimes called -- are free or cost a minimal monthly fee. After that, all you need
