Computer failure comes in many shapes and sizes. There are the fairly easy ones and there are the very difficult ones. Learning to know which type it is likely to be will save you time and make troubleshooting problems a whole lot easier.

The most serious of problems are probably those concerning hardware. When you hear the ominous repeating click sound of a hard disk in the throes of death, it's too late to panic; the damage has already been done.

Power supply units can often be the cause of problems in computers. You don't need a lot of experience to conclude that your power supply is no longer supplying power. Even if it is still supplying power, it may be underpowered and causing problems because of that.

Computers create heat. That's why they have a cooling fan as part of the assembly. Should the fan fail, or if it is inadequate because the manufacturer doesn't care, or if the under ventilation is inadequately provided for, you will experience all kinds of problems.

When a computer overheats it will often suddenly shut down. It does this to protect itself from over heating any more. However, it doesn't tell you that there is a problem beforehand, and that it has to shut down. It just does it. If your computer is doing this regularly, it could be an overheating problem.

Troubleshooting these kind of computer problems will require you to make an educated guess at what kind of problem it is likely to be. Pursuing that line of thinking will lead you on to other related components, and eventually you should be able to track down the real problem. For example, a problem with the sound card will exhibit itself through a sound problem and a video card problem will make itself obvious through the monitor.

Don't forget to check all the cabling and plugs first! Many a technician has been embarrassed after spending time checking everything only to finally notice a loose connection. Check the most obvious first when troubleshooting computer problems, if only to eliminate them as the source of the problem.

Sometimes troubleshooting your computer problems will lead you to a software cause. Perhaps there is a software conflict. This would likely show up soon after you installed a new program. In fact, if your problem is noticed immediately after installing a program, then that is the likely cause.

Try uninstalling the program. If that fixes the problem then you need to find out why before re-installing the program. Make sure all the software drivers are up to date before trying any more software installs.

Troubleshooting computer problems is usually never easy. It takes time and the simple plan of doing one thing at a time and checking to see what the effect is. If you do several things and suddenly everything is fine again, you'll never know what the cause was.

Always make one change, check, and if it doesn't work to improve matters, make another change, and so on. Being methodical will make troubleshooting computer problems a lot easier.
