If you have ever been the unfortunate victim of a computer failure, you have probably been left wondering, “Why does my computer crash when I need it the most?” Although it may seem like just an extremely unfortunate coincidence that your computer crashed right at hour 10 of that term paper you have been working on, the odds are good that the crash was not a coincidence at all. In fact, when you need your computer the most is often when you put it under a strain that it simply cannot take. Sometimes, it is entirely preventable.

The first thing you need to diagnose is the cause of the failure. At first, this can seem almost impossible. Especially if your computer has just stopped running all together. But every crash has symptoms and signals that may clue you in so that you can recognize them in the future. If you recognize the cause of the crash, you may be able to prevent it entirely or at least save your data before the inevitable happens.

When a computer is used to the very limits of its capability, it undergoes physical stress, and heat is one of these stresses. When a computer has been working for too long in an area with poor ventilation, the unit can overheat and just shut off. For some fortunate users, a computer may simply shut down as a form of precaution and you just need to give it time to release the heat before turning it back up. Sadly though, overheating can also lead to hardware failure, in which case, you would need to find a hard drive replacement. An overused computer can also be using more power than it usually does, and this could cause the power supply to burn out. You would know if this is the case if the unit does not turn on at all.

Another possible answer to “Why does my computer crash?” is software problems. For computer users who often browse the internet or belong to a large network, it’s advisable to use anti-virus software. But while, an anti-virus software keeps your files and your computer safe from the threat of viruses, this software may also cause crashes to your PC because of possible conflicts with other programs you have installed. Given this, it is very important that you read on the instructions of the anti-virus software before you even run them. A dirty registry can also put your PC in frequent troubles. To solve this problem, simply run a registry cleaner or do a defrag from time to time.

The early signs of a computer crash are easy to recognize: a hard drive making strange noises could be experiencing mechanical failure, and desktop errors you often encounter may be indicative of software conflict within the system. If you stay on the alert for these signs, you can do preventive measures to avoid a computer crash, or even just do a data backup of all your computer files before it is too late. Most computers are bound to fail sooner or later, but if you have a file backup plan in place, you won’t be left so helpless, and asking “Why does my computer crash?
