Problem with ASUS P8Z77-V Pro

I'm new at this so be nice.
I built my first pc using asus p8z77-v-le running on raid and gs700 power supply.
On startup the gs 700 fan runs for a second then dies olso intel cpu fan has a hard time starting. Tries to kick in for a few seconds then starts and keeps running.
everything else seems to be working ok.
Any help would be appreciated.
Thanks don22

  1. i have the same problem with a cooler master silent pro 800w and a p8z77v pro
  2. When I had that problem, I'm not sure what it was either but I found that If you completely unbuild the system, including removing the cpu from the socket and the motherboard from the case, put it all back together and everything was fine from then on. The person I sold it to has not had any problems since.

    Don't know why or what fixed it, but it did for me.
  3. well actually I've done dry start ( just the mobo and the PSU ) and it starts for 32-3 secs and then it stops so it's already "dismantled " but thanks for the reply
  4. you could try this to test the psu without the motherboard.

  5. @ varusad
    That's kinda like a rolling stop instead of actually stopping. Removing the cpu and all components is the idea, not just some of them.

    well, as i said before : i had just the power source and the motherboard , so no cpu , no gpuy nothing just the MB and the psu; btw it did the same with all the components installed
    tank you rfor your answer thou

    BTW thePSU is OK , i've tested on a different computer and it works fine
  7. update
    changed the mobo - got a msi z77mpower
    and using the same power supply i have the same problem -
    tested the PSU with http://www.corsair.com/en/blog/tes [...] wer-supply
