I installed a fan controller in my computer and after it installed my display no longer detects my computer and my USB keyboard and mouse wont power on (LEDs wont turn on in them.) Even if the controller isn't plugged into power the issues persists. What could be causing it to happen or how can I figure out what is causing it? The display is hdmi plugged into my graphics cards and the keyboard and mouse have USB plugs into my MB. The controller is the NZXT SEN-001L LX dual bay. These are the rest of the specs. The monitor is a flat screen TV. AMD FX-4100 Zambezi 3.6GHz (3.8GHz Turbo) (OC to 4.1GHz)

That's a very poor power supply.Could be the issue.
