my computer won't turn on, it's hooked up properly in a properly working outlet but i press the button and nothing happens. no lights, no sounds, no fan whirling nothing. i assume the power source went out? dell wants to charge me $40 to ''troubleshoot'' it and i don't have $40, if i did i'd have a more extensive social life than a $15 a month MMO. someone tell me if that's what's wrong or what else might be wrong?
