GA-Z97P-D3 (Rev 1.0): Reboot loop

[Domarije]

Hi,
I bought my new tower (Custom Build) in october last year and never had a problem since, and it is annoying that it is something as simple as the bios throwing the tower into a reboot loop. Here's how it plays out;
Turn it on
Tower turns of then on,
Beeps once (Good sign right?)
Display turns on, shows mouse and a flashing underscore (normal for BIOS to do),
Reboots.

I have examined the PSU and the CPU, and the USBs for scorch marks, tried clearing the CMOS, left the CMOS Battery out for an hour, unplugged everything, tried 1 Ram module. Everything under the sun and nothing.

Is there any recommendations you guys can make?

My specs are:
GA-Z97P-D3
Intel Core i7 4790K
ASUS GTX 770 2GB
8GB HyperX Genesis DDR3 1600MHz

Have you tried a different ram module, worked for me.

Have you cleaned it out really good of dust and so forth. I doubt it is heat if it does it right when you first turn it on but good to make sure.

Also did you try just 1 ram module in different slots and maybe switch ram module to see if it stayed with one slot or module?

I have tried both the modules in different ports, taken one of them out, still the same. I haven't tried de-dusting it so I will try that.

EDIT: Oh and I also tried dead RAM just to see the BIOS beep code and it was different from the good RAM I have installed, as it was 1 long and 1 short. Therefore making bad the possibility of bad RAM moot.

Do you have bios all the way updated. When bios first boots it is reading the hard drives and storage after cpu and ram. But it sounds like you aren't getting that far. When it happens can you enter bios by hitting the delete key and if you can hit failsafe defaults and reboot. If you cant then you might need to make the backup bios kick in.

Impossible for me to, I had it in Ultra Fast boot mode, so when the USB KB & Mouse kicks in that's when the OS is loading, I think I also disabled the PS/2 KB & Mouse as well beforehand.  Anyways I contacted my supplier and they are doing an RMA on it when they recieve it, if they can't Gigabyte will end up doing their own RMA, if they can't I'll get a replacement.
