I recently upgraded my pc and it won't start up unless I unplug everything in the back of my pc except the power cord. I can start it up only then. I also unplugged the pwr_switch on the motherboard, and touched the 2 prongs with a metal screwdriver to start it up, but it still only works when the peripherals are all unplugged. Sometimes it still works with the prongs and the power switch with everything plugged in, but 90% of the time it won't startup unless I unplug everything.
