Motherboard I have is a GIGABYTE GA-Z77X-UP4 TH


So I was trying to see if the new fan I brought would work with my pc so I decided I would try to test the fan and turns out its a MOLEX connector, I read that only 2 of the pins needed to get connected for it to work so i tried that.


As soon as I tried (didn't push hard at all) my pc turned off. I immediately turned it back on and tried to connect the fan that was already connected to the header and now that header doesn't work at ALL.


Now I have managed to change the wires and connect the fan upto another fan header but is spins extremely slow.


And the first header I mentioned still doesn't work anymore.


What should I do?

If anyone wants to help reply with your discord and we can call.


thanks in advanced
