Ubs plug in

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

Reasoning?

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)

Insert the plug into the Headphones output. Take a look at the User Manual: http://www.dell.com/support/Manuals/us/en/19/product/xps-8500

What's on the monitor? Any error message? Or is it just blank?

The Dell GX620 has 4 DIMM slots (2 DIMM slots on USFF chassis); Non-ECC dual channel shared2 DDR2 SDRAM system memory (533Mhz) up to 4GB max with 1Gb in each slot.

DDR 2 with 533MHz this is the RAM that comes by default for this model...

you can install RAM in size of 2GB per slot...

HI there Stephen,

Your Dell Optiplex GX620 has four memory slots which can accomodate a maximum of 4GB (DDR2). For the full information you can click the link below:

Please let me know if this answers your question. Thank you for using FixYa.

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.

try to replace the ubs cord, dont be afraid of opening the mic because wires are color-coded unsolder each wire then solder the same color from the other usb cord

try the bios settings is your monitor in a grafics card slot
also see if plug and play is enabled only use a keybard and mouse with a ps2 conection not usb

what wass the last thing you were doing before this happened
