No signal after installation of a new CPU cooler

I installed a Corsair H105 on my AMD FX 8350 today, and it was working fine, it booted fine and was running very quietly, but I wanted to play around with different fan configurations by connecting the fans to various different headers.
After doing this and returning it to the default set-up that had previously been working it is booting (fans spinning, HDD light on) but in doing this the monitor has stopped receiving signal from the computer and my mouse laser isn't turning on.
I have tried various different ways to fix this including:
Replacing/reseating RAM
Removing and replacing CMOS battery
Inserting GPU into different PCI slots
Reseated the entire system.
Unplugging and holding the start button.

None of which have made any difference as the display isn't receiving signal.
Is there anything I've missed or forgotten to do? Or is there just a problem with one of the components?

do you have a GPU?? if so, did you plug in the power to it?? Happened to me and I was worried.. found that I did not plug the power to the GPU and connected the monitor to it..

Thanks for your response. Yes I have a GPU but it is an older model without a power cable slot and its ran just fine without for about two years with no problems at all.

What I meant is that, if you got a power cable that you disconnected from your GPU, check to place it back.. just make sure that everything is connected and sitting in their ports firmly..
