New build powering up issues

[Shashman]

Hi,
Just finished assembling my new rig, everything's all connected up correctly AFAIK, however when I turn it on it only stays on for 4 seconds, cuts out, then powers up again, until I power it off. Also, the case fans spin, LEDs light up, but the CPU fan doesn't do anything but a small twitch

Specs:

Mobo: Gigabyte Z68X-UD3P-B3
CPU: Intel i5 2550K
RAM: 8GB Corsair XMS3
GFX: Inno3D 560Ti 448 core
SSD: OCZ Agility 3 60GB
PSU: Corsair HX620w
Case: Bitfenix Shinobi black windowed
ODD: LiteOn somethingorother DVDRW
Case fans: 2 x 120mm Xigmatek Crystal white LED, 1 x Xigmatek XAF-140 PWM 140mm white.

Could it be that I've connected the 140mm fan to the "PWR_FAN" 4 pin port? (I connected it there as that was the only 4 pin available on the mobo, the other 2 are 3 pin)

Halp

P.S:
The PSU has been used in another system so it's not that, as has the graphics card. Everything else is new/second hand.

But that's for the CPU fan surely

I have the CPU fan connected to "CPU_FAN" and 140mm case fan connected to "PWR_FAN"

EDIT:

*facepalm* I've just noticed that I didn't connect my SSD or ODD to the PSU.... Hoping that's the problem!

Just took out half the ram (2 modules) but no joy

It looks like the CPU fan wants to start, it literally twitches when the system powers on, but that's all.

Could it be something to do with the front panel connectors?

 

[Shashman]

Right then, done some testing with the RAM.

I've tested each individual module, and I've paired them all (every combination).

Individually, I found that one module was faulty. Another observation is that the modules only worked when in slot 1 or 3, not a single one worked when used in slot 2 or 4.

When paired, no combination of every module worked in any of the slots :/

Basically, I can only use one module at a time. What gives?!

 

[Shashman]

Yup, boots fine with one of the 2gig sticks.

I can't run 2, no matter which slots I use As for the faulty module, luckily there's only one, and even luckier that I got it for £4!

As for clearing the BIOS, and the rest of your post, I'm afraid it's been ages since my last build and I'm a bit out of the loop. Could you explain the process of clearing, plus updating the BIOS with the update you linked me to?

Cheers for the help so far!

Edit: Heh, simultaneous post

P.S. I'm guessing that just biting the bullet, selling the working modules and buying a single 8GB module could be a workaround?

Clearing the BIOS is very simple and there is two ways to do this:

Please refer to this document for the location of the battery and/or the CLRCMOS header (17):

[URL]http://www.manualowl.com/m/Gigabyte/GA-Z68X-UD3P-B3/Manual/207346?page=22[/URL]

1) Move the CLRCMOS jumper into the position to clear the BIOS. Leave it in position for at least 1 minute, then return to its original position.

2) Remove the battery for at least 1 minute, then replace (I prefer this method, just be careful not to damage the board removing the battery).

Try this first before flashing the BIOS. If you still have problems try the flashing procedure:

Put the BIOS file onto a PC and run the exe, with any luck it will prompt you to insert a USB stick or floppy. Allow it to copy the files over, then take the disk/drive over to the motherboard. Press Del to enter the BIOS and go over to the QFLASH utility, follow any instructions to flash the BIOS. Be very careful not to disrupt power to the board for any reason, loosing power during a flash can brick the board.

Your board looks to have dual BIOS chips so you're fairly safe anyway, and the backup BIOS will kick in if anything did go wrong.

If you do need to flash and can't for some reason just post back and I'll try figure out why

[edit]

Oh here is a list of supported memory, make sure the stuff you're using is listed:

Yup, I've seen the battery and the clear cmos pins, however there isn't an actual jumper, so how would I set it to clear?

I've read (in the past) that you had to leave the battery out for 20mins? Has the method changed then?

Thanks for the step by step guide, I'll give it a go tomorrow and let you know how it went

As for the single 8GB module, it was a workaround for the problem of not being able to use more than one module, should all this fail. They're not cheap though :/
