Gigabyte Z77X-UD3H, no power/led/sound
« on: July 05, 2016, 11:34:53 pm »
So i bought this Motherboard second hand and after setting the pieces up, it doesnt power up.
I decided to unplug everything and let only the mobo + cpu, and even removed it from the case to make sure it isnt a static problem. But still the same thing.

It doesn't boot, it doesn't make a sound, I see no leds on the mobo at all when I plug it in.
i did the trick to see whether my power supply works(green with black) and the fan of the power supply immediately turns so I supposed it isnt the power supply?
I do find it weird that when I tried to switch the pc On, my cpu fan turns for a second and then falls silent. Cause this would mean there is some power going to the cpu fan(ergo the motherboard)?

Hope you guys can help me :(

edit: power supply is antec earthwatts 500w
