When you own a PC it is much likely that you have some trouble with it some day or the other. It is not the case of just you. Each and every PC user has to go for troubleshooting someday or the other. It is not your problem at all.
The actual reason behind this is that PC is very sensitive and delicate machine. With all the complex working of software and hardware in a computer, there has to be still some good co-ordination missing, even today. You have to be a very professional or proficient in both software and hardware to run a computer without issues. This is impracticable in most of the cases.
So what do you do to troubleshoot your PC problems? Running to a professional every time you get a trouble is never feasible. And I am sure that they are not going to respond well, when you call the call center of manufacturers for even small things like creating backup files, etc.
