What is the typical charge for having a technician reload my operating system?

Rates vary depending upon your location and who you go to. I usually charge $50-$75 per hour, which is typical for my area. Doing a clean install of the OS as well as applying all patches and updates will probably be 2-3 hours, depending upon the speed of the computer and whether there are any hardware or driver issues. As a rough estimate, you're probably looking at roughly $100 or so.
