PC wont turn on

[gibbynator]

My parents were out of town so i decided i would bring my newly built rig up stairs while they were away. Brought it up stairs worked no problem. They get back bring it down stairs and it starts for a few seconds then turns off. Now nothing happens if i turn it on unless i unplug the power cord turn the psu switch off then on then plug it back which gives me a little bit of fan spin but nothing else. Here is my build if that is important. http://pcpartpicker.com/p/B6QBxr

Make sure everything's plugged in correctly. It's possible that a cable might've accidentally unplugged itself while you moved it.

Also, is your system POSTing (Power On Self Test) correctly?

i reseated most of my cords already( Sata cables, cpu power and fan, gpu power, the mobo power sw, reset, sw etc. cords and the mobo 24 pin still yielding the same effect. This is my first build so i am unfamiliar with POSTing sorry. It has a green light on the mobo when plugged in that stays on when i hit the power switch other than no leds are on.

Did you check to see if the front panel power connector is plugged correctly? if you reseated all of the cables you may have flipped the front panel Power Switch.

is the front panel power connector the plug that goes into the mobo? if yes then i have double checked it

Disconnecting both the Cpu and Gpu power plugs allows my pc to turn on but it must be both not just one or the other. Does this mean i am down a cpu and gpu??

Can you get in on onboard graphics?

[gibbynator]

Can you get in on onboard graphics?

how would i go about doing that

[MoDtEc]

Your mobo has a DVI connector. Connect your monitor with that, plug in the cpu power cable and try turning it on.

for checking the gpu use a second pc: one of your friends parents or something like that. throw it in there and if it runs your gpu is out of the line.

clear CMOS

[gibbynator]

cleared cmos and had no effect

[gibbynator]

using mobo hdmi still did not work

Is the PSU on? Is the wall socket ON? try another Wall socket.

Does the PSU fans work?

As i previously stated if the cpu and gpu power cords are removed then the computer will turn on so yes it is plugged in (unless i am working on it) and the wall socket does work. The PSU fan does work as well

[William12h]

Maybe faulty MB or the cables are damage or Broke the PSU somehow

would the led on the mobo still be able to light up if it was faulty?

[William12h]

Yes and no Depends what is wrong with the PSU if it is fault etc. If its powering the Mb but not able to Power the CPU and GPU then maybe its blown some capacitors.

Can you plug just the CPU in and it works?

No with just the cpu it still does not turn on

[William12h]

No with just the cpu it still does not turn on

Are you able to test it with another psu? like a friends etc, if it works in ther system then you know its your psu. But it could also be the MB or both the CPU and GPu which dont work.

[gibbynator]

i have two older computers one is from 2001 and the other 2010ish. The 2010 is broken (probably hdd failure) but im not sure if its psu will be suffecient to power my system

[gibbynator]

it is a 300w psu

[William12h]

Try it anyway, all you need to do is check that the CPU and GPU are fine, Even a 300 watt PSu will be fine since your not putting the GPU under load. just cause the CPU is like 140Watts and the GPU is like 300 Watts, it doesn't mean that is what it is using all the time, only under full load, So theorticaly it could use 0 Watts etc (but obv it will not and use something like 10-30% when the GPU is idling/not gaming.

 

You best of taking your Mb out of your case and leaving it on something like a cardboard box or that static paper thing to keep the electronics safe. (Taking it out is up to you but allows you to access areas easier) 

 

On your MB have your CPU, RAM and HDD etc installed but leave your GPU off. Plug in one of the other PSUs and power the PC up If It powers up then you know it is not your CPU or MB.

next turn it off and plug in the GPU, if the GPU, CPU and MB work then you know it will be your old PSU. If the CPU and MB works but not the GPU then maybe your PSU broke and fried your GPU.

Turns out the PSU of the old computer was also broken but the psu for my build was able to power the old system. So does that point to the mobo or the parts

Well ita likly something like the MB is damages or something else, But you cannot fully rule out that PSU until you find the cause, for all you know the PSU may work under little load then fail when it reaches X amount of Watts.

 

You could try your GPU in your Old system with the PSU and see if the GPU work, If so then you know its not the GPU.

If you are able to Try another Compatabile CPU in the MB and see if it works, If not then its the MB. Similarly Try your CPU in a Compatable MB.

 

Take out your CPU, leave in your GPU and everything pluged in power it and see if you get any POST beeps or anything at all. And check for damages pins on the CPU.

 

I think it is most likely be your MB.

i am going to have someone work on it cause the older pcs cant fit my gpu so kinda hard to test it out
