As the title says. Before you start reading, please check the video I uploaded with the problem: http://


I assume now you saw the video. So we have infinite boot loops and that weird fluctuating sound(This happened when I removed every component except the CPU. When RAM sticks were onboard, it boot-looped but sound was normal). Power switch and reset buttons don't respond during that period, I have to shut it down through PSU switch. Then when I turn the PSU switch on, I have to wait like 5 mins before it powers up again. Before that given time, if I press the PC's power switch, it does nothing until a few minutes pass. You can see that there's no monitor signal. HDMI cable is plugged on board and tested through VGA as well. The motherboard base screws are missing, thus I could not install it inside the computer case. Mobo it's placed upon its box it came with. I mentioned that because some of you may suspect the short-circuit scenario, well I believe that's not the case. My main suspect is the mobo though.

Things I did:

1) Tested 2 different PSUs. (The main PSU I tested, was 100% functional with the previous build)
2) Unplug, then Re-Plug all connectors.
3) Removed components one by one (RAM, VGA, Disks, Front panel headers), till only the CPU's left onboard.
4) Reset CMOS Battery.
5) Read a lot of threads but no clue.

Computer Specs:

Intel G4600
Gigabyte B250M-DS3H
(No point mentioning the other because there're not onboard)

So any solutions?

No solution but a suggestion

Sitting on the box the board isn't grounded, as it would be connected to the case, connected to the power supply. You might consider making a ground connection between the mobo and the psu.
