Computer problems

[Wraith]

I'm having a problem with my computer at the moment which I can't seem to sort out and I'm hoping you guys can help.

The problem is that my computer can't connect to the internet and when I run the "Diagnose connection problems" box that comes up it tells me to ensure that the modem is connected properly. I have checked this out and all the connections are hooked up properly so I'm now at a loss. I have the additional information:

The modem works - my X-box is connected to the same modem and accesses the internet with no problems.
It is not the connection port on the modem as I've tried the X-box cable in both of the ports in the modem and both work fine.
It's not the cable itself as I've tried the X-box cable between the computer and modem and that didn't work.
I don't think it is the connections on the computer itself as I've tried 2 separate firewire(?) ports and a USB port to connect to the modem and none of these work.
I have not installed/deleted/modified any new software after the problem started or soon before.
I have done the usual stuff like virus scan / spyware scan etc (although the definitions were a bit out of date as I hadn't used the comp for a couple of weeks and without the net connection I obviously can't update them.

I did have a recent problem with the power supply which I've had to replace and it was after I did this I first noticed the problem so I'm wondering if there could be a connection but I don't know.

Any ideas?

When you say "modem", do you really mean "router"? Or it is a two port modem?

What operating system? Vista?

I'm guessing that your computer used to be able to connect just fine but recently it's stopped connecting? Did it connect after you changed the PSU?

What firewall are you using?

Are you seeing the connection light for the cable?

What do you see when you type the following in the command prompt:

ipconfig /all

...?

What type of network card do you have? is it PCI? or one on the motherboard?

It is possible that the PSU dying has taken one or more components with it

I think I mean modem not router but I've never been very clear on the difference. It's a BT Home Hub (the older style white one if it makes any difference) with 2 firewire and 1 USB connector. All of the lights that are supposed to be green on it are green but it doesn't have individual lights for the different wires.

OS is Windows XP and firewall is Sygate Personal Firewall Free version.

It used to connect fine before the PSU problems started but has not been able to since I changed it.

I will try the command prompt tonight and get back to you with the results.

The motherboard has an onboard network card which worked fine. I then added a PCI network card (about a year ago - long before these problems) which also worked fine. I have tried connecting the modem to each of these and get the same error with both. I did wonder if the PSU had taken out these but it seems strange that it would kill both network devices but nothing else.

I get the following response

Windows IP Configuration

Don't know what any of that means but hopefully it'll give you a clue whats wrong.

Looks like the network cable is unplugged? Possibly a bad cable, did you use the same cable to connect the xbox?

That implies to me that the card isn't recognising that the cable is connected. Or your network drivers are fubar.

That should look more like:
