Ok I HAD a 5 year old Dell 4500 and the other day the thing just quit while I was surfing the internet. If you open the case the Idiot lights come on to show that there is power and you have the case popped open. Plus my keyboard lights up but I cannot get the power to come on by pressing the power button. I am using a Bro's tower until I buy a new one, but I would like to see if I really need to buy one. Any Ideas?
