Hi! I just got a new motherboard. It is the Gygabyte GA-Z77X-UD3H (rev 1.1). I replaced the old motherboard with the new one but when I turn on the power, fans start running and LEDs turn on but 2-4 seconds later, they turn off again. Like 5 seconds later, it tries to boot again but the same thing happens. This cycle is repeated until I power off the PSU. All through this process, the motherboard light remains on. Also, the LED that's supposed to show error codes doesn't show anything.
I made sure everything was connected properly twice and I had also taken all precautions against ESD. I tried powering it with only the minimal stuff (CPU, heatsink, CPU fan and one stick of RAM) to no avail. Next, I figured maybe there was something shorting somewhere but upon checking, I found nothing unusual. I even removed the board from the case and ran it atop a non-conductive surface but the same thing happened. I also reseated the CPU, thermal paste and heatsink and made sure that the CPU socket pins were alright. I even flipped the switch to run on backup BIOS instead of the main BIOS (I figured maybe the BIOS version could be incompatible to my CPU or something like that).
The PSU is good. It works perfect on another system. The RAM is also good, to my knowledge. Does that mean i have a faulty motherboard? Or did I short something when installing the board? Or is it a much simpler issue that's preventing the system from booting? Please help!
