You know people can either disassemble their PC, put it in their car, take it to a local repair shop, be told it'll take two weeks and will cost £150 only to find out that it will really take three weeks and cost £250 because their hard drive got accidentally wiped. Alternatively, they can log on to or call The System Doctors, send in their machine and have a technician fix the problem in a couple of hours for less, guaranteed.
