So today I was playing some Arma 3 and out of know where my computer turns off. I try to turn it on but noting happens. It wont post but what I did notice is when I turn it on for a split second the CPU lights up, I don't know if it is a spark or something. A few more things to note are, the power button on the motherboard is lit up I have tried to turn computer on through clicking that button same thing happens. My headphones are still getting power.

Hi spike,

first of all if you can List what brand of motherboard is in the system and the model number of the motherboard.

Most motherboards bought within the last two years have a cpu Led light.
That will light a solid red color if there is not enough power from the Six or four E-atx power supply block fitted to the motherboard to power the cpu socket of the motherboard with extra power phases.

If the case and the Led light is lit a solid red.
It relates to a power problem or power distribution problem from the Psu of the system.
The older the power supply used in your system in age of years the more likely is it may of failed.
It`s a good Idea to also mention what brand of power supply it is you have in the system as well as the...

It`s a good Idea to also mention what brand of power supply it is you have in the system as well as the total amount of watts it can out put.

And also exactly what brand of Pci-e graphics card you are running with the system , and it`s model number also.
It all helps to diagnose if the power supply is the most likely cause as to the problem.

But also check as much as the eight or four pin E-atx 12v power supply block is firmly seated and connected to the motherboard via the Psu.
And that the required 12v Pci-e power connectors required are also connected firmly to the Graphics card it`s self direct from your Psu of the system.

The first thing to really try is another PSu of the same or equal wattage output connected to the system if you have a spare one Spike.

Or at least borrow one from a good friend to test to see if the current Psu is the cause if quiet old.

This is my advice to you before panicking.
And to confirm if the power supply is at fault or the main cause.
Instead of blindly buying a new power supply unit for your system and a chance of wasting money if the Psu currently used is not at fault.
Still though post all the information about the power supply used, the model of the motherboard, it`s brand, and the graphics card details.

As a bit of solid advice to locate the problem part of the system you have.

PM me with the details for further help, if you wish Spike ok.
