Hi,

Since around 1998 all motherboards come with the LAN (network/ethernet) on board.
The port will be at the back of the Dell next to the USB ports, you can't miss it.



Regards.

Do you have an optical mouse, is the light lit on the bottom? try another usb connect in the back of your computer if you have one, try another mouse.

I'm really not sure what you mean by "P7 plug", and without knowing more about your system and OS... I generically searched Dell Support page for Dimension 2400 and found a page of driver downloads (76) (if you install, make sure you do them in order. instructions are on the page. just go to Dell support and put in your service tag # or search generically)What I did find is an owners manual, and if yours has been misplaced (like most of mine) just follow this link. P.S. I still don't know P7 but maybe the answer you need is in there. Best wishes and good luck. -jmattes I looked again, sorry it's a DC plug but I didn't see where it goes. There's a link for service manual there too. http://supportapj.dell.com/support/edocs/systems/dim2400/en/index.htm

The resolution for this is to go into the BIOS with the help of F2. Then look for the option USB Legacy devices. If it is enabled disable it or vice-a-versa. Also look for Boot from USB devices. Please disable that option. And select the first boot device to be the HDD (Internal hard drive)

have you tried using another mouse? if you've re-installed the drivers it maybe thats the problem is corupt system files and a windows reinstall may be required

Less expensive for recieving is simply the "usb stick" I would recommand a "ralink" chipset, (can be found in USROBOTICS and some less expensive brand like TOPLINK

a computer proffesion dosent need a mouse to wok on computer . the windows (logo) botton opens the strt menu . then scroll it with up and down arrows press enter to select . tab to switch between windows and drives . windows key+ e opens my computer . windows +d reduces windows

Liquid on the electrical circuits, causes bad things to happen.
Do not replace the computer, until you exhaust all of your options.
Did you try the most simple solution of replacing the mouse?
Have you tried starting in safe mode? (with new mouse)
Otherwise: When you get the computer to start
Go to your "Device Manager" (Right click on ‘My Computer', select 'Properties', click the 'Hardware' tab, click the 'Device Manager' button. Click the "Human interface devices", if there is one). If there is some kind of a "Warning" icon superimposed on the 'Mouse' icon or any other icon, there is your problem!
If no "Warning" icons then try...
One at a time...
Double click on any of the devices that have 'Mouse' in the listings.
Click the "Properties" tab; look for any "Warning" icons
Un-install the DRIVERS for THAT DEVICE only. See instructions below.
Click on the faulty device and hit the remove button, follow the instructions given by the program.
Shutdown, restart, the device will automatically reinstall by the "Found New Hardware" program.
