Computer completely shuts off and does not power back on

March 30, 2014 at 08:08:02
Specs: Windows 7
I was running league of legends which isn't an to intensive game, maybe 2 hours top, and my computer shut down without any warning or any signs of anything, a complete blackout,and it does not power back on fully, when I try to turn it back on , you can see that the fans and components start to move and it all powers up for about 1 second then it all just stops and does nothing, im not sure whether this is to do with the power coming from the PSU or not , there is a light indicating electricity going to the GPU , can anyone help ?

You need to supply some additional information. For a start, the full model number, if store bought or the hardware specs if custom built.

To me, this appears like a PSU failure... it's quite a possibility. A single bad capacitor can completely kill the PSU.

But to start from the top, as this appears to be a custom build: Did you check all the plugs on the rails feeding the motherboard? Having this wire(s) come loose can completely shut down your system as described, AFAIK. Many fans feed from the motherboard and no power, no fans, no system period. Light on the GPU showing power probably means that at least some of the supply wires are still working, but I still wouldn't rule out complete PSU failure. It does happen, even with the best brands.

get a new power supply with at least 80 percent power efficiency

You have a good power supply but it could still be defective. You also have a board with good components on it.

Be sure the CPU fan is rotating freely and is connected solidly.

Disconnect all unneeded external hardware.

Have you tried booting into Safe mode or booting to a bootable disk?

I suggest you remove the add in card and set up the BIOS to use the processor GPU. Your CPU and MBoard both support that. That will eliminate your Geforce as the problem.

No that's the problem , it doesn't boot into the bios at all, the power on is a mere split second as the fans and all components move for 1 second , nothing comes onto the monitor and I don't get any output from anything

Will it help removing a network card/ or Gpu itself at all?

I advised you to pull the add in card and run on the Intel graphics.
