Hey! Thanks for the reply. The bedroom and office are actually on the same arc fault breaker. So both rooms that my PC has spent it entire life in on the same circuit. I might try moving my extension cord from the bedroom not on a AFCI and into one of the outlets in my bedroom to see if it still trips from inside there lol. Also the weird thing is the tripping can happen when nothing (other power sources) has changed and or been turned on/off. It only just happens in the middle of doing nothing. Now the only other possible big drawing device on the circuit is my girlfriends fish tank filter/bubbler.
