Took it all apart and cleaned everything. Tried just hooking the PSU to the motherboard, switched on, the fan started on the PSU, there a little whirling noise and then nothing. So same problem as when everything is connected. so this problem is either the motherboard or the PSU.

Could someone tell me if it's normal for a PSU fan to turn for a second or two and then stop? It does that even when not connected. If it's not normal then the problem must be the PSU. If it is normal then it's the motherboard that is faulty.

Thanks
