Hi SwimFly84,
Ok, there is a possibility you didn't mount the motherboard properly.
Second of all, you could have also frogot the brass casing like screws that go intot the case. (They should come with the normal screws in the little zip-lock bag), They basically look screws, but they have a hole through them were the actuall metal screws go in).
When you bought your case it came with screws in a little zip lock bag with all the rest of the stuff.
The brass thing are like screws but screws can go into them at the back
(I know I said it twice, But just making it clear)
You have to screw those into your board because right now you only have screws right to the board driectly.
This means your board is touching the case which leads to a short circuit.
You have to put those brass heads into where ever there are mounting holes on the case then you have to put the motherboard on the brass heads and screw the board onto the the brass heads.
If this has not been done, and the fans don't run properly, its probably cause you have a short on the board.
Thats why it keeps shutting off!
Hope this makes sence.
Try that, It should work. Is your power supply an ATX power supply?
Do it, and Let me know how it goes.
Best Regards,
