I have recently installed Arc-fault interuptor breakers, they are code for all bed rooms. they trip when an arc is detected on the circuit.

Glad you got your problem fixed, i would recomend getting a qualified electrician to look over the entire house. Also you can buy the NEC code book to see what the current code is. While you may not be required to bring it upto current code, i'd recommend doing it.

Also (my opinion) I'd recomend having a dedicated circuit for computer equipment, but definatly not on the same circuit as a dishwasher, fridge (dedicated by code), microwave, or other large appliance.
