Antec Three Hundred Tower Gaming Case
G.Skill 8GB(2x 4GB) Memory Kit – PC3-10666 (1333MHz) DDR3 – 240-pin DIMM – Timing 9-9-9-24-2N – Unbuffered – Non-ECC (F3-10666CL9D-8GBRL)
Intel Core i5 2400 – 3.10GHz
ASRock Z68 EXTREME3 GEN3 Motherboard
MSI GeForce GTX 560 Ti Twin Frozr II Overclock Video Card –
PSU Antec Neo Eco 520C

Plugged in the 12 pin power. And also the 8 pin power to the ATX pins.

Beginning to think a faulty z68. Bought new PSU and still no noise when you power on. We are talking no beeps, lights, fans, nada. All connectors in 12 pin and 8 pin.

Swapped CMOS battery for new one. No luck.

Z68 has a direct power switch on the motherboard. That doesn't power on so I don't think it's got anything to do with the system panel header cables.

Any luck yet?

I'm getting the exact same RAM and MB as you have. The RAM is not on the list of compatible DIMMs on Asrock's site for the MB, so I am concerned it may either not work or have some other problems. I hope that's not the case.

Please update.

Hi
Still no luck. I have tried to power up using only this with no luck
- PSU, mobo, videocard, RAM

Also tried swapping CMOS battery

But you are definitely right in that it may be the RAM. I don't know how I can check it - will the mobo still power on without anything attached?

Jech, you really should follow rolli59's link and guide, if you need to RMA anything, time is going, you should hurry and find what's wrong so you can send it back in time if necessary. Don't bother intalling the GPU, use the one on the MB instead for now.

By the way, you can't fault the motherboard or RAM until you can say 100% that the PSU is not at fault.

Tried only PSU and mobo. 24 pin and 8 pin plugged in.
No LEDs or any noises.
PSU works, power cable works, system panel header plugged in but also used the power button directly on the Z68.
No go.
RMA it is.
