I currently have 3 Dell computers on a network. There is also 2 printers. If someone is doing some thing on computer 1 and i go to print off of computer 2, it shuts computer 1 all the way down, not just a restart. Each computer is plug into a surge protector on a different wall outlet. What is causing this to happen? Could the wall outlets be on the same curcit and it is overloading it?
