? you may want to check the wall socket where your cable plugs into the wall, many times a loose connection there will cause small unnoticed electric arc that can cause problems like that. electricity needs good firm connections. but the red wires if i remember right are( 5+ volts ) and could be a indication that something is pulling to much power,so i would guess that the power supply has a weak compacitor or failing, and changing the power as you suggested is the best first responce.
