My dell GX620 desktop does not power when ever I plug in the network (RJ 45) cable. Also if the system has boots to desktop, and I plug in the network cable it automatically goes off.

1) Does it have a separate Ethernet Card, or is it integrated?
(Part of the motherboard)


The Dell Optiplex GX620 comes with Integrated networking.
The chipset is a Broadcom 572.
It's part of the motherboard, and you plug the Ethernet Cable into the back of the computer.

However, you could have a separate Ethernet Card, plugged into the white PCI expansion slot on the motherboard.

A) If you are using a separate Ethernet Card, replace it.

B) If you are using the Intergrated networking of the motherboard, (Plug Ethernet cable into back of computer), use an Ethernet Card instead.

White PCI slot.

You have a short circuit when you plug the Ethernet Cable into the motherboard. Don't use the motherboard networking, use an Ethernet Card.

2) Plugging an Ethernet Cable into a computer that is on, = No.
It is not a Plug N' Play item.

(Not stating this is what you are doing.
Just posting in case you are. Burns out the Ethernet chipset on the motherboard)

Dell optiplex GX620 desktop has an ethernet port on it, that is not an adapter, I cannot connect to the internet, I downloaded and installed a driver for a wireless ethernet adapter, but that has not...


1) You can download a wireless Ethernet adapter driver all day, but if you Do Not have a wireless adapter card installed in your computer, the drivers do you no good.

Or if you do not have a wireless USB adapter plugged into a USB port.

Example of a wireless adapter card,

Example of a wireless USB device,

Example of an Ethernet adapter card,

If you are just going to hardwire the computer, just buy an Ethernet adapter card, (PCI version), and install it in your computer, (On the motherboard), in any available white PCI slot.

IF it is the Mini Tower model.

The Desktop, Small Form Factor (SFF), and Ultra Small Form Factor (SFF) computers, are too small in width for a regular size Ethernet adapter card.

They need a Low-Profile Ethernet adapter card,

This is for a Dell Optiplex GX620 Mini-Tower computer,

Scroll the page down until you come to the bold blue heading - System Board Components
This is an illustration of a Top view of the Mini-Tower's motherboard.

16 and 17 point to two PCI slots.
This is where an Ethernet adapter card that is the PCI version, will plug into.

PCI slots are White in color.
An example of a basic PCI slot, ( 3 are shown),

If you do decide to go wireless;

1) Wireless networking operates at half of the speed of wired networking.

A computer that is wired directly to an Ethernet adapter card, is twice as fast on the internet, as a computer that is connected wireless.

2) Make sure your Router is capable of wireless.
Make sure the wireless router has a built-in Modem, or that you have a separate Modem.

[ For DSL.
Phone line connects to Filter. Filter has a place for a telephone cable, and an Ethernet cable.
Ethernet cable connects to Filter, and other end connects to Modem.
Ethernet cable goes from Modem to Wireless router that does not have a built-in Modem.

Phone line connects to Filter. Ethernet cable from Filter goes directly to wireless router, that has a built-in Modem.

Computer has to have a USB wireless device, or a wireless adapter card, installed.

Dear Sir, I am first time share my problem in this forum & I hope I will learn much more. I have dell computer minitower gx620. I am using this computer from 2 years, Now problem is, When I connect...

Sorry to say but any liquid other than mineral and vegetable oil will permanently damage a motherboard. So the urine may have caused the damage, or the contact cleaner could have. The Orange/Amber lights on Dell systems mean either the RAM is not seated properly which is usually an easy fix, just take them out and put them back in, but if that doesn't work your motherboard is dead, and you will have to inquire dell for a replacement. Good Luck, and thanks for using Fixya as your Go-to source for information.
