Hi,
A house next door to us got struck by lightning. And ever since then my ethernet port hasnt worked.... I have a Dell Slimline PC with Vista Basic Home. So I went a bought a PCI Ethernet Card cause everything else works fine. Installed the card which i had to take the little metal thing off of the card to get it to fit and no lights come on, then I installed the card in another PC and the card is good. Decided to buy a USB to Ethernet Adapter installed it with the correct drivers and still nothing... In device manager my ethernet and USB to ethernet card says that both are working properly... I just have run out of ideas... Any help would be greatly appreciated... Thanks in advance!

The bracket that you screw down into the case... Kindof helps keep the card in place... Since the PC is a Low Profile PC there was no other way of getting a PCI card regular sized in there.

It sounds like you may have got some electrical feed through the network cable that damaged the southbridge chipset on the motherboard.
If that is the case the only fix is a new motherboard.

If the onboard LAN doesn't work, The PCI slots don't work so you can't use a LAN card, the USB doesn't woek so you can't use a acapter , then you basically have a typewriter that will play offline games. :flowers:

If the southbridge chipset , which controlls the PCI slots & USB ports, is damaged there is no fixing it.

If the house next door got hit by lightning it probably fed through the lines to your house.

Now, There IS one other possibility. :thumbsup:

If that is the only computer that works [is hooked to] your cable modem there is the possibility the modem is bad.
If you have other computers working through a router hooked to the modem then the modem is good & the computer is bad.

What about the Power Supply? Could it be possible that a part of that was damaged and therefor it isnt getting enough power to the PCI and USB ports? Keep in mind that my keyboard and USB mouse work fine which doesnt really make sence unless there isnt enough power getting supplied to the USB ports to power the adapter.... Hmm :thumbsup:

OK, Let's backup a minute.

You said the USB ports don't work.
Now the USB KB & mouse work.

Alright, we'll take it from the top.

Go to the Device Manager
Locate Network Adapters & expand the listing
Right click on each that is listed & on the menu click Uninstall
Once you are finished restart the unit & let the Network adapter reinstall
Hook the cable to it & try it.

Well, I have 2 more suggestions before I go back to replace the motherboard.

Do a system restore back to a date before the problem started.

If that doesn't work,

I assume you are posting from another computer hooked to the modem you are hooking the problem computer to in order to go online.
If you are not there is a possibility that the modem is bad & the computer is OK.

There are a few places to get a motherboard.

I suggest you use the service tag code off of the unit on the Dell site to see if you can determine the exact model of the motherboard so you can try to find an exact replacement.
It would save you some potential problems.

One last suggestion.
Since the motherboard isn't working right anyhow go to the Dell site, get the newest BIOS update for it & see if you can flash [update] the BIOS.
If it gets messed up worse you really haven't lost anything & you MIGHT get lucky & fix it with a fresh BIOS.
