So, since the first step in diagnosing and repair any type of technology is being aware of exactly WHAT you have. This guide is focused towards computers for the most part, seeing as few electronics need to be profiled in the same way that a computer does.
For Windows users:
The best way to find a good system profile is using the DxDiag command from your ‘Run’ menu. To run DxDiag, click “Start” -> “Run” -> type “dxdiag” (without the quotes) and hit enter.
An example of a DxDiag window
DxDiag is a executable file that will bring up a window with all types of information about your computer. Unless you are very interested in understanding the types of hardware that you have under your hood then simply click the Save button at the bottom of the window and save the file as a .txt.
This file will give me the relevant information about your system so that I can properly diagnose and instruct you.
For Mac users:
In Mac OS X the system profiler is the best way to go. To open the system profiler, open Finder -> Applications -> Utilities -> System Profiler
Then go to File -> Save As, then select “Rich-Text Format (.rtf)”
Again, this will give me the relevant information about your system so that I can properly diagnose and instruct you.
