I have a computer that needs to run on a 220VAC (60 Hz). It has an OCZ Modstream 450W PSU, and works fine on standard 110VAC power. When I flip the red voltage selector switch on the back to 220 and plug it into a 220V outlet, the power supply fan comes on as do both the power and HD leds on the front panel of the computer, but the system does not boot up. It kinda just hangs there. Power-cycling doesn't do anything, and it works fine on 110V. Is there some "trick" to getting it to work right on 220V?
