AutoTest is a popular product that is designed to run a series of tests on a computer, designed to identify problems. AutoTest can be downloaded for free to see if it will run on your PC. The main problem with this is that it is very difficult to find out exactly what you are downloading. I have tried out AutoTest numerous times and have found a large number of errors with this software. There are many free tools available that you can use to try and discover what is actually going on with the system, so you can identify it and make a final decision about the application.
When you first download the free version of AutoTest, you may find some error messages appearing, but the problems are likely to be very minor. The best advice I can give you is to take the time to play around with the program for at least 10 minutes to see if it causes any trouble on your PC. Once you have used AutoTest, if it causes any problems then you need to take steps to get rid of it. If you get a solution to a problem, you should try to document the error message as this will give you a good idea of where you went wrong and which action to take next.
You also need to bear in mind that there are many utilities that will enable you to install the free version of AutoTest. It is always a good idea to have the full version of AutoTest in case you need to perform some extensive testing on your system. It will save you time in the long run.
