Was there a question?

Yes!
Is my computer beyond rescue!?

Today I found other cd for the computer.
I can not connect to any external source. The wireless PCI-Express card is not working. LAN cable doesn't work.
How do I make Internet work? (I.e. the LAN that is!)

Regarding all the ?'s in device manager, looks like you are missing the chipset drivers... The link below should work for the Optiplex 330

Thank you!!
Unfortunatly, no difference... The Air-Plus Utility does not open!

I'm out of ideas. I've installed a clean XP twice from the cd to the computer. The diagnose cd does not show any defects...
Network is not working.
What could be the issue...!?

The network is not in the chipset, it is a broadcom, to get wired lan working you need this

Remove the WIFI card, and get the model number or FCC ID# and google them to find out what the card is, and then search google for XP drivers.

You need a computer tech!!! They make things all better, no fuss/no muss.

Goombawaho, that made me laugh out loud. :)

Well........... I wasn't trying to be solely funny. I don't try to do plumbing or brain surgery. Know your limitations, know your strengths, act accordingly!! Words to live by.

Have you tried getting the device drivers from the Dell site? The UK site is

There may be a swedish site. Just look for optiplex 330

Look for the service tag - if this is not on the machine, it will be coded in the BIOS. Using the service tag is often more useful. On the older machines, it told you exactly what hardware your machine had and where you could find the drivers for them.

Did you reinstall the system using the Dell reinstallation disks or from a version of XP you got from somewhere else? The Dell reinstallation disks should just install everything.

No, the Dell disk won't install everything. They include a "system resource disk" that has the other drivers on them. I've done this many times - the Dell CD is no different than a regular XP CD. And it's no more successful in adding all the drivers than a regular CD.
