Yea sounds like a Motherboard issue, just bad luck

The hard drive is a very likely suspect, it's the most sensitive part to mishandling. When a drive is running, the g-forces required to damage it are much lower than when it is parked.

Captain hit the nail right on its head, i.e. most probably your HDD is the suspect, try to turn on your PC by detaching the HDD, if the system POST, then you need not to look elsewhere.

In addition to above, also ensure that graphic card is properly seated (if it is installed in one of those casings with plastic locks, it can get affected by the 'bumping').
