When fixing your computer going through tech support can be a hard and confusing process, but by following the next few tips you will enhance the experience you receive.
For a start you should try to work out what is wrong with your computer, do not just call up and say your computer is broken, if you come with generic problems you will receive generic solutions. The more accurate you can be with your problem the better, this may involve a bit of research on your part, but it will speed the whole process up. This leads nicely into my next point which is be precise with your language. Try avoid generalized words like `it` or `thing`. So instead of just saying my internet is not working try describe the situation as well as you can. This will lead to a much faster service.
More importantly is to just try to remain calm. The tech support is not trying to sabotage you and wants to help you find a solution as quickly as possible, so by remaining calm and pleasant you will receive a better form of support. It is quite an obvious statement to say but it is probably a much better idea to butter up your tech support instead of berating them, they did not break your computer and they only want to help you.
The key tips are to try to do research into your problem, avoid generalizations and just try to remain calm. This will improve your overall experience, giving both you and your tech support a much easier and faster time.
