Did I damage my motherboard??

[Vulgrim]

I recently got a new case. Last night when I got done setting everything up and turned on the PC I had a lot of interference in my audio coming from my sound card. So I took it out to try to readjust it away from the wires that were touching hoping that would fix it. Here's the problem though. My computer was on when I took my sound card out. Then a few seconds later the computer shuts off and now it doesn't detect my graphics card or sound card. Have I damaged my motherboard? What do you think?

Might have, think I'd bench it and put together a piece at a time, have a guide that might help here:
