Hi all,
New to the forum, I apologize if this is in the wrong place - hope you can help.
Just built a new PC and having issues getting it going.
When turning it on the fans all start up including the processor fan, the phase LEDs light up and the monitor comes on showing the Gigabyte Motherboard set up screen. So far so good.
However within about 15 seconds the computer turns off before restarting and continues in this loop. Furthermore none of the USB ports are working and so I can't use the keyboard at all to enter the BIOS for the few seconds available before the restart loop. I also receive no beeps but this may be down to the Mobo I'm using not having an internal speaker.
I've followed the steps from TomsHardware to no avail;

I've now resorted to bread boarding the system and only attaching the power (20pin and CPU 8pin) cables to the motherboard, the CPU + Fan with one stick of RAM (also tried with no RAM) and the system continues to restart as before. I've used the cable from the PC case to start the PC and also a jumper just to confirm its not a case issue.
I've also cleared the CMOS using a jumper and removing the battery for a few seconds. I have also tested the PSU with another system and it works fine which makes me doubt it is the PSU at the root of this.
My part build is the following;
Intel i5 3570
Gigabyte GA-Z68XP-UD3 Motherboard
Corsair CX430
I'm feeling it could be a faulty motherboard? anyone have any ideas?
