Power down, unplug, open the case.

Double check all connections, card seatings, RAM, and jumpers to ensure that all are fully and firmly in place.

My thought is that the air blast knocked something loose.

Also check all ports. Ensure that no debris was blown inside and is now interfering with connectivity.
