CPU fan gives short tick, then stops, pc doens't boot

[helices]

Setup:
- MB: Gigabyte GA-H77-DS3H
- RAM: 2x Kingston ValueRAM - 8 GB : DIMM 240-pins - DDR3
- CPU: Intel Core i5 3470 / 3.2 GHz
- PSU: Corsair VX450 Watt
- Samsung SSD 850 EVO 500 GB
- GPU: Asus Nvidia GTX960 turbo

When I turn on the computer, the case fans and GPU fan spin, and the CPU fan gives a very short movement, like its trying to wake up. After about 10-15 seconds, the other fans stop. After a few more seconds, the process repeats. During this time, I am not getting visuals on my screen (no input) and periferals are not lighting up.
In the first round of troubleshooting, I thought it was the PSU, since I'm running some pretty heavy hardware on a modest power supply (especially the GPU) and it looked like the MB/CPU fan was not getting enough power. So I unplugged all "unnecessary" power consuming things (GPU, one stick of RAM, peripherals, SSD, case fans) and still have the same problem: fan gives a little tick, then dies.
I then cleaned out all the dust from the case, fans, CPU heatsink. Found lots of dust though, so it definitely didn't hurt to clean everything out.
Cold booting doesn't fix anything, altough the trouble did start after a series of hot days.
My MB does not have an onboard speaker, so I can't do any of the beep-troubleshooting, which is too bad.

Any help?

I'm posting this in Motherboards because the MB currently seems like the one causing the trouble. Any advice is greatly appreciated!

I assume that you tried resetting the CMOS.

I assume that you followed the steps in section 5-3 of the user manual.

You have checked that the CPU power cable (4pin) near CPU is correctly installed.

I would try replacing the PSU with a new one (perhaps buy a 650W one so you can use it on your next machine).
If not that, then as you suspect, it could be motherboard or CPU.

Have you tried with the onboard graphics only.

Something similar happened to me with a new PC build, just after I added a sys fan extension cable. The problem was while fitting the new cable, I'd partly dislodged the motherboard power cable. Pushed it back in place and the PC went again.

Presumably the partial connection was enough to make the fan 'tick' but not enough to supply the whole motherboard.
