Ethernet card caused computer failure

By jan.c ·
Lightening followed ethernet cable to my computer which was off at the time. I replaced the burned ethernet card but the computer will not start. Lights on monitor and keyboard come on but will not go off. Sounds as if the computer is running butthe monitor remains dark. Have tried a different keyboard, monitor and mouse. I have another computer I could move the hard drive to but do not know if I should set it up as a slave??

I feel that lightening has hurt your motherboard. Motherboards can't be repaired in the field. They must be sent back to the factory. Sometimes lightening will take out a lot of hardware. I suggest that you check each piece with a known good one. Ifyou want to check the hard drive you would put your spare one in as master. Disconnect all the cards and drives except the video card and see if your computer will START to come on. If it doesn't you can try a different video card. But I think it isthe motherboard. Hope this helps Frank

I would also check my memory modules. Try another piece in your machine to see if that was the problem. Frank

remove the hard drive from the suspect computer and install it in a machine that you know is working.
The master/slave part will depend on the other machine you install it in. If the other machine is set up as master/slave then set the suspect drive to slave but if the other machine has the hard drive set to auto(cable selective) then just set the hard drive to cs.
after you install it watch your boot up messages on the screen carefully, hopefully you will see that the drive is detected. If your settings are correct and the drive is not detected , it my be fried also

Assuming that your ethernet card was a PCI slot card, I would start by removing all other PCI cards.

If the system still does not boot, then the PCI bus on the motherboard, and possibly the entire chipset is damaged.

From a reliability standpoint, I would replace all of the hardware in the case. If the lightning took out the PCI bus, then it is very likely that everything has been overstressed.

Take the drive, and install it as the primary slave, or either secondary drive. If the drive operates, back up all of your critical files and settings.
Then purge the data from the drive, and add it to the scrap heap.

The problem is that lightning damage (like static electricity damage) may not show up right away.
If you attempt to reuse parts from the dead PC, you may become a member of the upgrade of the month club, as the stressed components fail one after the other.
