So last night I installed vista on my computer. So now I am dual booting XP and vista. Got me so far, good now get this! So I am playing around with vista for about 30 minutes or so and then I hit shut down. So windows does it's little shut down stuff then I hear the fans and hard drive shut off but then I see that the leds in my fans and the display in the front of my computer are still on, but are very dim. There should be no lights or anything on at this point. So now I am thinking what the heck? So I go hit the power button and the computer will not turn on... I left it unplugged all night and then tryed turning it on today and get the same result... Any help would be greatly appreciated
