I called Nerds On Call to repair some basic problems I was having with my computer. They sent an on-site "technician" to "fix" the problems and downloaded all sorts of their software on my machine. The computer's performance actually got worse! They sold me on a service where technicican's can site your computer to repair it.

Don't use them! It's a rip off! read full review »
