New build computer won't boot or beep.

post #1 of 58
Thread Starter 
I just built a new computer, and when I start it for the first time, it won't beep and it won't post, nothing on monitor.

Main power connector plus the 4 pins are connected to the main board.

Connect two 6 pins power connectors that say PCI-E 1 and PCI-E 1 to the video card. And video card are properly place in the PCI-E x16 slot.

Water block are tighten on the CPU, power connector are connect to the 4 pins molex, and the RPM sensor are connect to the CPU fan header.

Two sticks of RAM and place properly in the dual channel mode. Slot 1 and 3.

All fans are connect and working.

What is the problem?

Here is my build:
https://secure.newegg.com/NewVersion...er+final+build

I didn't plug in the speaker plug to the mobo, that's why there's no beep. Bad news is, this full tower I got doesn't have the speaker plug. It only has power switch, reset switch, power LED, and HDD LED. Is this the reason why it won't post?

Also on the mobo, all the lights on the phase led is on.

Description from the mobo manual:

PHASE LED, the number of the lighted LEDs indicates the CPU loading. The higher the CPU loading, the more time number of lighted LEDs.

If all the lights are on, does this mean CPU failure?

I also took the mobo out of the case, and only run it with cpu, watercooling on CPU, video card, and ram, still no go.

Try switching RAM in different slot and still no go.

What could the be problem? CPU? Mobo? RAM? the watercooling system? or the video card? Please help me, I'm so desperate.

You said you plugged the main plug plus a four-pin plug into the motherboard. Quad cores require an additional eight-pin ATX connector, this is the first thing that I noticed. Maybe you just forgot to mention it, who knows. But if you did forget to connect it, MAKE ABSOLUTELY SURE that you plug the 8-pin ATX connector, and NOT the 8-pin PCI-E connector. It technically shouldn't fit, but if by some fluke it did, you'd probably destroy your motherboard and cpu.

The first thing you really should do, especially with troubleshooting posts, is to fill out your system specs in your User CP. This will help all of us all that much more.

Might be obvious but to you have your power switch lead connected to the front panel header on the motherboard correctly?

Also, you mention the "main power connector" as well as the 4-pin connector. Is this located near the CPU? If so then is it a 4-pin connection or an 8-pin that you're using the 4-pin plug in? A lot of newer motherboards I see have an 8-pin connector now.

Which revision of the motherboard do you have? If you have rev. 1.0 or 2.0, you'll need BIOS version F11 or newer... Check which rev. of the mobo you have. If it's 2.1, it should work fine.

Other things I can think about is that there might be a short circuit somewhere in the system. Did you use standoffs in the correct spots when installing the mobo?

Also, I personally would have tested the parts before installing it all with the H2O loop...

EDIT: yep, you need an 8-pin connector, and not a 4-pin

Tell me exactly which are on or atleast you think are on:

CPU
MOBO
CPU FAN
OTHER FANS
VIDEO CARD FAN
HARD DRIVE DVD DRIVE

if nothing beeps or whatever and cpu hd and everything is working then it could be the video card, does your monitor say that it can't find signal? If it does then it could be that you didn't switch your monitor to digital or whatever signal the video card is outputting.

I plug in the 24 pins main power, and the 4 pins right next to it. There's another 4 pins that say ATX_12V on the mobo. Which I didn't plug in anything.

The mobo can handle an 8-pin connector. The openings for the other four pins are covered. Just pop the little cover off, and plug the 8-pin connector in.

You'll need those other four pins also (making the total of 8 pins). The connector is right next to the 4-pin connector you used. Again, just pop off the little cover, and connect the additional four pins.

I can't find this 8 pins on my mobo. My mobo is GIGABYTE GA-EP35C-DS3R, and it's rev. 2.1

The PSU come with the 24+4 pins main power connector, and extra 2 four pins that say CPU-1 and CPU-2. Should I plug in these two 4 pins?

The other four pins are right next to the one you already connected. Tehre is a little black cover hiding them. Remove the cover.
