It can be really hard to solve computer problems if the only thing you've got is a description and nothing else. This is why Windows 7 integrated a Problem Steps Recorder which, if activated, records every action the user of the computer takes with a screenshot and a brief description of the action. Open it by typing psr into a Run... prompt:
The record is saved as a zipped mhtml file, usually only readable by Internet Explorer but also in Firefox if you install the proper add-on (it is called UnMHT, find it here). It displays all the descriptions of the steps taken along with the screenshots made and is also not too large in size, making it easy to share it with someone who might help out with a problem.
