PC Boot loop, no BIOS.

Hi,
I've got my computer (built it myself) for three weeks now. Everything worked fine, yesterday I shutted down my computer (from Windows 10 Professional). When I tried to start it this morning, it didn't boot. It gets on for three seconds, turns off, then turns on, turns off, and turns on. The bootscreen with the boot options doesn't appear (I mean the Gigabyte screen). First, I thought it may had something to do with my psu, but after a test (connecting the green and the black wire), I realised it was working. I've already read the threads advising to get all hardware deconnected, and trying to add them one by one to see what's the problem. I'm planning to do that, but first I wanted to ask you guys something. I have got a Gigabyte motherboard which has got a stroke of red led light on the left, if I remember it well, that turned on directly when I booted my computer in the past, my cpu fan, and the gpu fans do turn on, the gpu is connected to the motherboard, and directly to the psu as well, the cpu fan is connected to the motherboard. My four case fans connected directly to the psu work, but the one connected to the motherboard doesn't. So I think it maybe be the motherboard which isn't working properly. Anyone an idear?

Hardware configuration:
Gigabyte z97x gaming 5
i7 4790k
Evga Gtx 970 ftw
Corsair cs550m (?)
Crucial ballastix 2x 8gb
Samsung evo 850 256gb

Windows 10

First off, try a cmos reset. I would lay blame to motherboard, and/or, power supply. The CS series are not the greatest units.

After reseting cmos the motherboard went on again, and after ten seconds the boot was cancelled. Second time I tried to boot it worked. Everything is working now, now low voltages, normal tempratures. I hope it's fine now, if not I will post again. Thank you for your help!
