Issue with power supplies.

I moved my CP to a different room. Being a good steward I felt a little cleaning was necessary. I removed the side panel and blew a little compressed air thru the device to remove some of the dust. Put it all back together and that's where the trouble starts. If I have both power supplies connected, upon pressing the power button, all the fans kick on like normal, but then they all drop down to an idle speed and the PC never boots. If I unplug the 230w supply, upon powering up the unit, everything comes on, but the GPU fan runs at max speed continuously, but the unit boots up as it should. It's kind of weird, but it seems like it may be performing a little better, although a bit noisy.
