Hi, The problem i'm having includes 2 computers, 2 ethernet cables, and 1 modem.

One of the computers runs windows vista and the one i'm having a problem with is the
"emachine T3256" which runs windows xp.

When i connect the vista computer to a ethernet cable then to the modem i add an additional
ethernet cable to the open slot on the modem and then connect it to the "emachine T3256"

Heres were the problem occurs, When i turn on the modem, about 30 secounds later the
"emachine T3256" screen turns black but the computer is still powered but i'm not able
to do anything but hold down the power button to turn it off manually.

note (the computer works fine when the modem is turned off)

I was just messing around though and have pinpointed the problem to be related with my
NIVIDIA nForce MCP Networking Controller.

I've checked windows updates for updates and already have the most recent.

The Funny thing is that i have done this before with a older compaq computer instead of the
newer "emachine T3256"

Just so you know im not trying to split a internet connection between to 2 computers, but
only to create a local area connection.

The modem i'm using is a Actiontec GT704WG which has worked before the new computer "emachine
T3256" was added.
