Diagnosing computer problems that often result in sudden – and sometimes not so sudden – failures of a given system can be a complex task. Computer diagnostics consists of several tests on the computer system which includes, both the BIOS and memory, the software and, in some cases, even the hardware that is attached to the computer.
Most commonly these types of problems will occur when your computer is down to very low resources, which can either be a low amount of RAM, or low disk space. These conditions are very common, and generally result in your computer running very sluggishly. This can easily be fixed, however, by performing a defrag your hard drive (or disk defragmentation), and get rid of some programs and files that you no longer need or use.
Almost all types of computer diagnostic software can find and fix just about any problem that you may be having. A diagnostic task will normally start off with BIOS examination, and continues from there. PC diagnostics software can determine a lot from the BIOS; from the common settings to those that have a major impact on both boot up and performance.
No matter what you do, you should never modify or tamper with the BIOS settings, as it can lead to serious problems. If you do plan to modify or mess with your BIOS, you should always create a backup first, just in case something goes wrong. Keep in mind that BIOS settings can be very tricky, although they are responsible in large part for with your computer performing well. If you have never been in the BIOS, you really shouldn’t be modifying anything inside of it.
Depending on the diagnostics program you are using, there will be several different features available. For many years two of the most popular were Norton Systemworks and PC Doctor. Both of these programs still offer full diagnostics software, good for fixing just about any software-related computer program you can imagine.
Once you run the program, you’ll be able to select the diagnostic test that you are planning to run. Some offer you a full system scan, which will scan your entire computer and then display any problems that may exist. After displaying any problems, the software will normally give you an option to go ahead and fix it. As long as such problem is nothing serious, the diagnostic software can generally fix it and indicate to you that “no action is required” (on your part).
The more complicated problems, such as hardware failures or hard drive crashes, are totally different in terms of identifying the problem and the recommended action. Such complex problems will require knowledgeable and experienced technicians with an aptitude to rebuild the hardware. In these cases the diagnostic software will report hardware problems to you although in most cases it will be unable to fix it.
There are other computer diagnostic software programs you run after starting the computer or rebooting it, which are capable of checking everything from BIOS. These program types are great, although the the ones mentioned earlier (Norton and PC Doctor) are still superior. They offer far more features including defragmentation, cache cleaner, and the option to delete your temporary Internet files. These features are great to have, especially if you aren’t the technical type.
For more reasons than one, computer diagnostic software is the ideal way to find and prevent problems within your computer. Norton Security Suites offer Ghost as well, which is an ideal way to back up your data. You can back up certain files, or just go ahead and back up your entire hard drive. These security programs are very easy to use, even if you are completely new to computers. For everything they offer the user – computer diagnostic programs are the ideal way to prevent problems before they happen.
