New Build: Fans fire up for 2 secs, then nothing

Hardware Hub Build a PC

Hi All, 

Looking for some help. I just assembled a new gaming PC, this is the first computer I've put together in like 15 years, so lots has changed. Anyways as far as I can see everything is connected correctly, according to my motherboard manuals instructions... When I try to power it on, the mobo lights up, fans spin for a second or two, then nothing, except mobo lights remain on. No video siganl, etc. etc. I've tried disconnecting everything except the PSU, Memory, mobo, And CPU Fan, same result. Ive tried 1 stick of memory, same result. Tried other stick only, same result. Made sure the memory slots were the proper ones to be used. Also tried popping out the little circular battery for a minute and popping it back in. Same result. Not sure what else I can try...Im thinking bad PSU???

Specs are:



PSU - Corsair TX750


Intel i5 4670k @ Stock


Asus Maximus Gene VI


Patriot Viper PC3-12800 1600MHz - 2x8gb Dimms


Western Digital Caviar Black 1tb HDD


Samsung Evo 250 GB Ssd


No Video Card Yet.

Thanks guys! Any Help would be very much appreciated ;)

Okay so this is wierd. I've determined that the only way I can boot to the Bios is if I unscrew the mobo from the chassis and just let it sit like that in the case. Which suggests that the pressure caused from screwing in the mobo is causing a short somewhere? Also it takes two attempts for the PC to boot to Bios. And the first time it booted to Bios it reported a CPU fan error. The next couple times no CPU fan error reported...


NO idea whats going on here, lol...

Motherboard standoffs ? Are you mounting directly to the case without using the stand off mounting screws .

standoffs should look something like this

guy probably has bent pins or missing pins. what error code are you getting?

I had a similar issue but this was after I OC'd it and messed with power settings (it's fixed now...)

Check to see if ALL and ONLY the right standoffs are in correctly

Do you have a PSU from another system you can use to test it?
