HD 4890 CTF No display

So I took my HD 4890 out of the case to blow some dust off the fan/heatsink, after I re-installed the card I now get a CTF led light on the card. I have no display whatsoever. I dont see how it could be getting that hot instantly so any suggestions/ideas would be greatly appreciated. Thank you.

The fan is spinning?

Sure you connected the psu to the card? I once spent like 30 min checking everyting possible and it was that

Lol, Figured out what was wrong... pretty stupid but anyways the switch on the back of the PSU was on the wrong watt/voltage. Never thought that would have a diffrence.
