My computer is about 2 years old, got it 2 years ago on christmas, so it's fairly new. Everything in it is about 2 years old except my brand new Video Card that I got a few months back.

While playing R.U.S.E BETA with a friend of mine, my computer just shut off completely and now refuses to turn back on. I've tried alot, For example so far i've unhooked everything from the computer except for the vitals.... tried to power on... and nothing. I use my computer every day, and no problems have arised until now.

When I press the power on button I hear a tiny whiz then nothing from the power supply, also the LED lights on my motherboard arent lit up at all. And when I plug my power supply in, if i listen closely i can hear the quiet vibrations of the electric current going in, so i do not know what is wrong.

My Specs:

GIGABYTE E8500 Motherboard 3.2GHz

4GB RAM

600W Echo Star Power Supply

ATI Radeon HD 4890 1G DDR5

Windows XP 32 bit

Any help would be appreciated.

Are they turning when you plug it in?

The PS is shot and gone to [b]Silicon Heaven.[/b]

Now for the really bad news I don't know this PS and most likely when it died it sent some nasties from the mains into the inside of the case and fried everything inside there. With all Name Brand Power Power Supplies like Antec they are designed to protect the internals from the crap and junk on the mains so they sacrifice themselves rather than allow nasty spikes inside the case. The cheaper no name PS do not do this and as such when they die the computer is turned to trash.

You can try a new PS in this and see what if anything happens but if it's killed the M'Board when you apply power the new PS is likely to expire so you need to understand that to prove that this unit is shot you will destroy a new PS. ;)

My PC didn't restart after an image restore a couple of days ago. No fan action, lights, POST or anything. Since it's still under warranty I called support. Of course once I had them on the line and tried starting it it started.
I may buy a PSU myself to avoid future hassles, warranty or not. I figured that the PSU isn't the best but I didn't know that it could smoke the motherboard/CPU.
Thanks.

yes a power supply takes in AC current and
basically converts it to a regulated DC to run the motherboard, HDD, and any other drives, case fans etc. All at different voltages / watts. So when they die most that
dont offer an internal surge protection will
also fry the motherboard. I have seen cases
where only the MB was destroyed and not the HDD or other drives.

Unplug the Power Lead from the mains and then press the Start Button on the front of the case for 10 Seconds. This discharges the capacitors in the PS and on the M'Board. Then plug the mains lead back in and see if it starts now.

If it does the Capacitors inside the PS are going off and you need to replace the PS. I personally only like the Antec PS's as I've seen one stop a 11KV hit when a tree fell onto the Overhead Transmission lines bringing the 11KV lines into contact with the low voltage mains. When this happened every electrical device in that neighborhood was destroyed and the computer that the Antec PS was in shot flames out the Fan opening and set fire to the curtains behind it. That was the smallest part of the damage to the house and the ceramic cook top had to be dug out of the ceiling before replacing the ceiling. No description of the cook top needs to be provided as it needed replacing. :D

The computer on the other hand just had a new PS fitted and a Monitor and it worked perfectly for the next 3 years till it was replaced. Not something I would suggest to demonstrate how good these Antec PS are but it was certainly a pleasant surprise when the system actually worked. ;)

You said you computer is 2 years old, but you got a new video card.
Did you check that the PS has a little extra Watts that the Video card works?

The most computer you buy over the counter, don't have a power supply that is able to power anything then what you have in the case, so it's likely that you slowly burned you power supply to dead.
