Upgraded video drivers, now HDMI won't display. Please help.

Hi everyone, thanks in advance. I am losing my mind. Just built my first system (i5 2500K, Gigagbyte UD3 mobo, 8 gigs dual channel ram) and everything has been great. I plugged it into my 46" HDTV via HDMI and again, everything great. I installed Vista (for now) and then began installing software. Everything worked until I updated my Catalyst drivers to the latest version. During the install, I lost my picture on the HDTV and have yet to regain it. I have the system working on my old LCD, but as soon as I plug in the HDMI cable neither screen displays anything. I have tried other HDMI cables and I have tried other ports on my TV. I am using a crappy Radeon HD 5550 temporarily, until I replace it. Any ideas what the problem could be?? Is my motherboard in trouble? Graphics cards shot? Am I just an idiot? Thank you very much.

I should add that originally the system would POST to the hdtv, but now it does nothing. My TV will say "connecting..." and then no signal. I am just praying that my new parts are not damaged.

Sorry for all of the posts, but I will add again that I just reseated the card and it is now booting up properly. If this is fine then that is fantastic, but should I be worried about any of my parts having problems? If it's the card that is suspect that is fine, but if it's anything else (mobo) I'll have to RMA it.

if its working now, I really doubt any damage was done. You are more likely to harm it by touching it (static electricity).

Thanks, I think everything is working now.
