Replugged fan wire now computer won't turn on

[coolmint65]

So when I woke up today I turned on my computer and it ran like normal for a few seconds then one of my fans in the front of the case made a weird noise and slowed down almost to a halt so I turned my computer off and decided to unplug the fan wire and replug it into a different connecter and now it wont turn on, I've tried plugging it back into the original connector but no luck, any help?
The image shows the fan wire in the original connector and I tried plugging it into the connector on the left
