Well, my friend's machine is running an MSI K7T266 with a Athlon XP 1600+ on Windows XP. It was brought to me apparently of a problem with their modem card, which in fact had been struck by lightning (I can prove that with the hole in the ceramic chip.) None the less, I installed a brand new modem, but the computer didn't pick it up. (A U.S Robotics type) and so I took out the new one and put the old one back in, to install any drivers that might be attached to it. It apparently didn't pick up that one. After going through many slots, (the Ethernet card still worked fine the whole time) I finally switched places of the Ethernet card and the modem. Then and only then did both function together. Why is this? Did the lightning damage the south bridge or what? Should I start suggesting a new motherboard, or just let it run?

Hi Mipsacri,

It is possible that when you moved the modem and lan cards that the resources (I/O and memory ranges) used before the swap may have changed allowing the cards to work together. I have seen this a lot with sound cards and lan cards.

Electricity - Lightning follows the path of least resistance. The strike the entered the modem had to get to ground somewhere. There are integrated devices that are suppose to destroy themselves before lightning can hurt the rest of the computer, but that surge still entered the computer. I would definitely trash the lightning damaged card. Did you notice any melting of the slot, or damage to the copper connector on the system board? If you any any further problems... my mind would always return to the system board. Still, if it aint broke, don't fix it?

Good luck

Rigel
