Computer won't power up Tags: CPUs Power Up Computer Last response: August 7, 2010 5:30 PM in CPUs Share Pinetree357 August 7, 2010 3:03:41 PM Hello, I have a Dell 5100 that when the power button is pressed it will not power up. The green light on the motherboard is the only think that powers on. Do I need a new power supply or is it most likely totally fried and I am SOL?
