Lan drivers

It is like that when i start pc, but when it passes windows logo it goes off

In that case:

Two types of trials...
1. Reboot in Safe mode w/ networking. Does that make a diff?

2. Is there some way that you could check a couple of things in the hardware? For example:

Plug the LAN cable that now goes into this computer, into another PC/LT to be sure that connection works?

Add a simple lan card to your current system and see if that does run on this cable?

Nope cable is not the problem

Then you have two options (i think):

1. borrow/buy a cheap lan card and test OR
2. Do a boot only install with a Ubuntu usb or cd disk....

if your LAN works with ubuntu... you'd he pretty sure it is W7 drivers and not HW or BIOS.

So then the problem is with your lan card. Get a new one,install drivers from the CD(with lan card should go and cd with drivers) and post here feedback. :)

I have tried with ubuntu. Its not working... I will try with another card

That kind of proves it, doesn't it

Good luck on the card and let us know how it goes....
