CPU cooler on correctly?
It may be an automatic shutdown due to cpu cooler fan connected to wrong port, not connected at all, or incorrectly attached.

Any beeps?

James Manns · 18 Jul 2010 at 11:13

its got a waterblock on, one of my fans is plugged into a cpu fan port, should i move it.
and there is no beeps

Take the motherboard out then place it back in. Something might be shortcurcuiting it.

Shorting on the case?
Have you got the "other" power wire in aside from the 24 pin?
Memory / GPU seated right?
GPU power in?
Reset the Bios

Obvious list, sorry, but the most common hiccups.

You getting any fan spin up? Lights on the mobo?
You installed the spacers correctly to lift the mobo away from the case?
Whats the specs for your system?

Might sound silly, but I had problems with my first build like this. Turned out the bios didn't like my USB keyboard. As soon as I unplugged the keyboard, it booted as normal

ill try all of the above and get back to you .

thanks

How's it going?

James Manns · 18 Jul 2010 at 18:22

took the usb keyboar out and that did nothing,
took the pwn rear fan out of the cpu fan socket, did nothing.
do i have to put spacers between the standoffs or something ?

It happened to me on my first build... :rolleyes:

No, you don't need spacers.

James Manns · 18 Jul 2010 at 19:53

so what should i try next ?

Burty88 · 18 Jul 2010 at 20:03

Could be useful to know the specs (what mobo etc...) of the build.

Had a similar problem to you (well, power error beeping on start-up) took everything bar the PSU out of the case and built it on the floor, reseating the RAM, GPU and CPU in the process. Made sure all the seating screws were screwed into the case fully and then put everything back in the case.

Could try this - takes a while but it's worth it.

PS. As someone suggested on my thread, put the motherboard on an antistatic wrapper when it's out of the case.

my mobo is a gigabyte GA-P55A-UD3
cpu- i3
ram - corsair ddr3 2 x 1gb 1333C9
hard drive- 500gb western digital black
psu- 780w ocz modx

8 pin power cable for cpu connected.
Memory in the correct slots, did this on my build.
Also try a CMOS reset.

James Manns · 18 Jul 2010 at 21:19

ram is in slots 1 and 2 and the 8pin is connected, and cleared cmos.

RJC · 18 Jul 2010 at 21:24

The memory needs to be in the 2 white slots, are these 1 & 2.

James Manns · 18 Jul 2010 at 21:25

yeah they are, in the manual it says something about dual channel being in 1 and 3 ??

James Manns · 18 Jul 2010 at 21:25

actually there in 1 and 3 ?

RJC · 18 Jul 2010 at 21:30

Ah cheers, hate when this happens

Couple of other options is trying only 1 stick of memory or running the board external to the case, unless you already tried.
