For $89/month, one can go to CBT Nuggets (
www.cbtnuggets.com) and obtain video training on obtaining your CompTIA A+ certification. That will educate you on how to repair PC hardware. You can then take courses in Microsoft and/or Linux and educate yourself on how to install, maintain and fix the software.
I am of the opinion that with a weekly schedule of 5 to 10 hours per week, one should be able to educate themselves in both hardware and OS install and repair to the point that they will be able to exceed the skills offered by Geek Squad. So for an investment of $270 and 60 to 120 hours of your time, you can obtain a valuable trade craft, reduce your pc costs and pc repair costs.
No, it is not for everyone, just thought I would share.
