He told me what I had already thought, that the power surge went right through the surge protector and blew my power supply. That was almost a given, considering that my machine was currently comatose. That isn't such a bad thing, necessarily. Since my buddy has the technical expertise to install a power supply himself, and was willing to do it for free, the cost to me would be minimal in both time and money. Of course, that wasn't the whole story.
Power surges are notorious for causing major damage to sensitive PC innards.
So I trundled the comatose critter down to the local techie repair shop and dropped it off with them to troubleshoot. I knew they'd charge me a fairly hefty fee just to look at the thing, which they did. What I couldn't be sure about was whether or not they would deal honestly and competently with the problem. Two days went by, and after several phone calls to ascertain their progress, I finally got a report. Your power supply is gone, of course.
