First many thanks for any and all help as this is my first time posting. I replaced the hard drive on my dell 9200 dimension with a WD blue cav this am. Took a while as I'm pretty green at this but managed to get it up and running and windows xp downloaded. Problem is I couldnt connect to internet ..so went to the dell site on my laptop plugged in the service tag and downloaded both the most recent bios and chipset software installation to disc then downloaded it to the dimension. Ran both independently of one another rebooted and still am getting yellow ? marks in Device manager on Ethernet Controller, PCI Device and video controller ... what am I doing wrong here??
