yeap, i'm part of a network, but that's no problem. i'm experienced enough with it. it's no big deal. I did change the nic just in case. Some times a bad nic can give you some problems (heck, i had big troubles with a nt computer and a cdrom drive

)
The real order of troubleshutting was:
1. Updating the motherboard drivers, usb drivers, etc with the mb manufactor drives.
2. updated the graphic card drivers by the manufactor drives
3. Updating the so with all the microsoft update said it was needed, besides the ie sp1 and the directX 9 drives.
4. donne a complete check on the disk (including surface)
5. changed the network card (because it was just to be shure if that long time of waiting wouldn't be by looking for some net drive or something. Also tryed to startup the computer without net adapters and drivers but nothing changed.)
i know it's some win driver that in getting on my nerve. If i boot in safe mode all go whell. If i work around with the msconfig, and checkout the drivers of win.ini and system.ini, all of then it go ok. All the others i get hang up with the 40 minuts boot

!!!!
This way to strange and i've been around for sometime now!
