Don't really know what to do, new with computer building and all. Put together my computer (specs below) and I am encountering an issue where the lights and fans will come on for half a second then turn off. This happened last night (post build) and then somehow it started to work at one point and I was able to install windows and the drivers for my motherboard. Upon installing google chrome I had to reboot for some changes to take effect. This is when the latest issue has begun and I can't seem to do anything to try and help it. I have attempted to reset my bios but I may have not done that right. I am just using the intel integrated graphics for now until my card shows up.
Thanks!

Welcome to Bleeping Computer!

 

I recommend you breadboard the PC motherboard.

Here is a video on BBing ...  .

 

Hope this helps!

That is pretty much how I have my motherboard running right now, still can't get it to turn on longer than half a second

Go down to one stick of RAM. Remove any other peripherals that aren't necessary for powerup. Try it again.

You may have to remove the CPU and examine the pins and the MB receptacle for damage/bent pins/debris.

Inspect the entire MB for leaky capacitors, especially around power plug inputs.

Use a known good PSU.

 Let us know.

So I got it to start again by pretty much redoing everything, catch is I have to mess around with the wires holding them in different directions everytime while constantly holding in the power button to get it to start? Any clue as to why this could be?

Is the motherboard property grounded by standoffs?

I believe so as it is now starting and running, but it will only start initially with wires in a certain position, after that I can mess with everything and it stays on.

This may sound even more weird, but if I rub the ac'97 audio adapter to the metal cage of the power supply fan it will start 100% of the time....

Which wire bundle are you messing with to get the fans to run? Is it the same bundle every time?

Something seems to be wonky with the grounds. Make sure the MB standoffs are not conductive,,, the washers/standoffs should be brass, ceramic, or plastic.
