I never really dared to dig into electronics like this. I had a nack for breaking things when I did. As an example, I purchased a Pentium machine back in the day. I had a feeling it was running too hot (or maybe I was trying to over-clock, I don't recall). But I decided to build a simple PCI card. So simple, in fact, that it just had a 12v case fan on it. I wired up the +12v pin and the ground pin to the 12v +/- of the fan. Then I plugged the PCI board into the PC. It worked! Except, it was now the only thing in the PC that worked. After removing it, the machine no longer worked. I returned it to the shop I purchased it from and they informed me that I must have had a surge. Everything was destroyed. The CPU, the RAM, the Video card, it was all gone.

The Sega Mega drive was a very robust machine and it did survive numerous short-circuits over the years and even today it still works!. but yes, I have blown numerous PC-motherboards over the years though... I guess that comes with the trade! One time I damaged my motherboard that was powered-off by using the vacuum cleaner to get rid of the dusts from one of the fans. The spinning of the fan resulted in a power-surge that damaged my motherboard :-(
