Have a Dell XPS 8700 that I purchased in October of 2013. The other day while my daughter was doing her homework the tower just shut down. Will not power up at this time. The green light on the back of the power supply is not illuminated. The yellow "Aux Power" light inside of the case is on.
When I press the reset button, next to green light, on the back of the power supply the light comes on the fans in the case operate an the optical drive powers on. So, is it the power supply or is the motherboard kaput? Or is there some waay to reset things? Tried the "hold power button down for 25 sec" thing to no avail and also left it unplugged overnight.
