The Tower has no power; I can't turn it back on.

\015 My computer is just 16 months old and I just recently had a new Motherboard installed (PCI Network adapter was not working) approximately 3-4 weeks ago. I've only used it 4-5 times when I begain installing 3 Windows software/programs off the internet. I noticed that it was taking my computer an extremely long time to download these programs; more than 1-1.5 hours. Eventually, I saw that the computer off. I tried to turn it back on but their was no power; it wouldn't turn on. I disconnected the power cord for a few minutes, but still no power. But my monitor was working okay as well as the modem for the internet. Do I have to get a new motherboard???? I don't have a clue what's wrong! HELP!\015

Answers :

First...check that your power supply is working. There should be a small light...usually green...illuminated somewhere on the motherboard when the computer is plugged in but turned off. No light equals dead power supply. Also check for a loose or dislodged cable inside the tower. Could be the MB installer didn't push a cable onto the pins firmly enough and it simply fell off due to the vibration and air flow since you've been using it. Try removing and reinstalling all of the cables just to be sure you don't miss the loose one. Then check that your RAM cards are firmly seated. Remove and reinstall. If you don't have any lights sounds or beeps after this, you may indeed have another MB failure. But there are other possible causes, so don't yell at your MB installer. Let them look at the computer to find the problem.
You may have to replace the motherboard, as well as check your power supply.Do you see any from of life when you hit the power button?Is there a light on the motherboard.Unplug the power conector to the motherboard.Plug the AC plug in press the power button for twenty seconds,see if the fan spins on the power supply.If not it may be a bad power supply only.
