New build won't start, PSU chirping sound

[Hacksaw907]

Hi everyone,

So I just put together my build. Not necessarily "new", but I just set up a WC loop for it. Here are the specs:

i7 2600k
Asrock Z68 Pro3-M
Agility 3 240gb
ASUS GTX 680
8GB DDR3-1866
Antec HCG-620M

Watercooling components:
MCP35X
3x Cougar Vortex PWM fans
RX240 and RX120
Heatkiller GTX 680 waterblock w/ backplate
EK Supreme HF

The thing is, it won't start. An oddity I observed is that every time I flick the switch to turn my PSU on, it makes a short chirp sound. Other than that, there's no activity from the system when pressing the power button.

Now, I know the PSU works (used the bobby pin trick to bleed the loop). I've also tried running it with just the CPU, GPU, SSD, and disk drive with no luck. I've verified the front panel connectors are correct (twice), and ensured all the components were seated properly. The only thing I could possibly think of that could be a problem is an 8-pin extension I just put in for the motherboard connector. However, I'm wondering if there is anything else that could possibly be the issue, as the connector is buried behind a radiator, and so I would need to take down the entire loop to get to it.

So yeah, I'd appreciate any help anyone could give me. Thanks.

EDIT: Well, it's not the extension, as I just took it out. So now I'm stumped. I've tried booting with the following configurations:

- CPU/Motherboard/memory with GPU unplugged but still in the socket
- CPU/Motherboard/Memory with DVD Drive and GPU
- CPU/Motherboard/Memory with DVD Drive, SSD and GPU
- CPU/Motherboard/Memory with DVD Drive, SSD, GPU and pump
- Everything, obviously

Also, could it be a shorting issue? I wouldn't think it could be a problem as it booted up fine while on air, but I guess I shouldn't rule anything out. Also, during the build, I grabbed the motherboard with my thumb resting on the VRM heatsink near the CPU. Could this have crushed them? Not sure if they are fragile or not.

Anyways, any help is really appreciated, since I'm lost as to what it could be.

Try Moutherbord 8 bin connector and 24 pin. Unplug and plug them back in .

Yeah, that isn't it. Tried re-seating them, and no luck. I even removed the extensions to rule it out.

I'm gonna try to boot it outside my case to rule out shorting. If that doesn't work, I'm just gonna assume my motherboard kicked the bucket. Unless anyone else can chime in on other possible issues.

Would the backplate for the cpu waterblock be the culprit??
Thats the only thing you've added that actually comes contact with anything.

CMOS clear and battery out for bit?

Any beep code at all?

This is true... I'll check the backplate to see if it's touching anything on the motherboard/case. Hopefully some bigger spacers can fix it if that is the issue.

Usually I'd do this only if it booted and there was nothing on the screen. But I guess I don't have anything to lose by trying it, really.

Nope. It doesn't even boot. Just a chirp when I flick the switch on the power supply, and nothing happens when I press the power button.

Really appreciate all the help, btw.

So yeah, two months later, I finally figured out the issue haha. It was my gpu backplate. Turns out it was touching some solder pins on the rear of the card, causing it to short out the entire system. At first I thought it was my motherboard since it would not boot after the cardboard trick, but I almost dropped a deuce when my replacement board refused to boot too. Luckily, the backplate shorting the card didn't kill my motherboard this time, and the system is now running flawlessly .

Thanks everyone for your help on the matter. Really appreciate all the effort to help fix my issue.

Glad to see it is working.
