If thing were shut down then chance are much better that the Pc is OK.
Some systems have power running thru them even after they are shut down,
unless the cord has been unplugged. This is for power on features.
So it may have taken a hit. Some surge protectors warranty agianst
damage that gets throught them.
You are welcome here, should you have any problems we can help with.
