i just finished building my computer but when i press the start button the fans and led's turn on and then it all shuts of 1-2sec later. I've tried reseting cmos, swaping ram slots, testing with only 1 ram stick, checked and double checked the cable routing. :/

Double check to make sure your CPU is seated properly and check to make sure the CPU fan is connected properly.
You may end up having to pull the CPU out, double check the pins and plop it back in.
Is it "POSTing" at all?
Make sure your CPU fan is plugged into the pin header for the CPU and you didn't accidently plug it into a system fan pin header leaving the CPU pin header empty. Don't laugh at me, I've done it before. Also if you are not using all of the system fan pin headers, make sure you are using the pin header designated as sys_fan_1 (or something similar)
I know the fans are plugged in to the right spots but ill take out the cpu and put it back in when i get home. but do i need new thermal paste if i remvoe the cpu fan?
Technically, you should clean it and apply new thermal paste but, if you just put it together you might be okay. If you have thermal paste I would go ahead and re-apply just for good measure.
I'm trying to think what else to check... I'll update here If anything else comes to mind.
Hopefully your board or cpu weren't DOA.
i bed 10 bucks on a grounding issue. take the motherboard out of the case, set it on a cardboard box and see if it powers on. if it does, you probubly screwed the mb to the case and didnt use the standoffs....
if not. reseat your ram, then your cpu. also, make sure your cpu power is connected as well.
"you probubly screwed the mb to the case and didnt use the standoffs...." xD yeah...no i defo used the standofs.
It's fixed now! it was a faulty cpu power cable
Was it the connector on the cable?
no idea i just swaped from the 2x4 pin to the 1x8 pin cable and it worked perfectly,
P.S. i'll probably be back when i crash the computer from overclocking XD
Ah Ha!
Sometimes when using those connectors one or the other may not seat properly and you won't even notice it.
Glad you got it figured out though.
