The next, fifth one is, whenever we see any error messages after something gone wrong we should take out time and write down the messages so that when we call up the tech support we can mention them exact what we are actually seeing on the screen. The sixth one is, sometimes the cause of our computer problem is something that changed in the computer or some incident that has happened recently, and we should always make a note of that such as an addition of new hardware or deletion of a software or a power disruption or addition and deletion of a service or any upgrading of software. Sometimes changes like this can cause some unforeseen problems with other things that may or may not seem to be related to your problem. When you're talking to your tech person, make them aware of any changes or additions you made before you started having problems. They'll be able to tell you if these changes are related to your trouble. And the last one is that we should always keep a note of the people we are talking in the whole process of the tech support, how many times we have been transferred or what they have done to diagnose the problem. It comes in handy the next time you face the same issue or call up the tech support.
