To tell if windows is already activated go to start...run and put in "oobe/msoobe /a" without the quotes. Then hit ok.
If windows is activated, it will tell you.
Next: you are missing the mainboard chipset drivers. That is why you have errors in device manager.
We can fix that. It will take some investigation.
Do you have a driver cd? If so that will have the chipset drivers that we need.
If not, we need to find out what computer you have. I believe (if I'm in the correct post) you said a dimension 3000. There should be a service tag on the computer someplace. With that, we can get the drivers from Dell.
I was able to get the reinstall disk from my relatives. It is all from a Dell system so I don't know if it will work. I might give it a try though
. If this is a restore CD, it needs to be for the exact Dell that you are trying to restore. The restore will reformat and wipe out the entire
drive and you will lose the other partitions.
